微生物CLSI文件集锦(你想要的都在这里)

微生物CLSI文件集锦(你想要的都在这里)

微生物CLSI文件集锦(你想要的都在这里)说起临床微生物的CLSI文件,大家首先想到的就是CLSI M100S——《抗微生物药物敏感性试验的执行标准》。

但是其实,与临床微生物相关的CLSI文件很多,截至2017年7月,已多达43个。

下面,小编就给您简单介绍一下吧。

1、M02-A12:Approved Standard中文:抗菌药敏试验的性能标准英文:Performance Standards for Antimicrobial Disk Susceptibility Tests内容与解释:介绍药物纸片扩散法的质量控制标准和最新折点标准。

2、M06-A2: Approved Standard中文:脱水MH琼脂的评估程序英文:Protocols for Evaluating Dehydrated Mueller-Hinton Agar内容与解释:略3、M07-A10:Approved Standard中文:需氧菌稀释法抗菌药物敏感性试验英文:Methods for Dilution Antimicrobial Susceptibility T ests for Bacteria That Grow Aerobically内容与解释:描述了肉汤稀释法和琼脂稀释法,而且还包含这些方法的标准化操作流程和CLSI推荐方法的性能,局限性,适应性。

4、M11-A8:Approved Standard中文:厌氧菌抗菌药物敏感性试验英文:Methods for Antimicrobial Susceptibility Testing of Anaerobic Bacteria内容与解释:在过去的几年内,大部分厌氧菌的耐药表型都发生了很大的改变,导致了许多菌种的经验用药的面临很大的挑战。

对于厌氧菌,琼脂稀释法仍然是参考方法,对于调查研究和科研同样都适用。

而且其他的方法的对比标准也进行了说明,肉汤稀释法也应用于临床实验室,但是现在对脆弱拟杆菌和一些抗生素没有标准。

具有可调控的多孔通道,可以容纳多种极性㊁体积不同的客体分子,因而常作为探针载体用于荧光传感中[2]㊂2008年,挪威奥斯陆大学的C a v k a 研究组[3]首次报道了一类以金属Z r 为中心㊁对苯二甲酸(H 2B D C )为有机配体的刚性金属有机框架材料,命名为U i O -66㊂与其他MO F s 材料相比,U i O -66具有特别的热稳定性和化学稳定性[4],晶体结构可在500ħ下保持稳定,其框架结构可承受1.0M P a 的机械压力㊂U i O -66在水㊁苯或丙酮等溶剂中可以保持结构稳定,并且还具有很强的耐酸性和一定的耐碱性[5]㊂曲利苯蓝(t r y pa nb l u e ,T B )是一种常见的偶氮类染料,可用于给棉㊁麻㊁蚕丝㊁化纤制品染色,并可作为纸张㊁皮革等材料的染色剂[6]㊂由于死细胞的细胞膜不完整,短时间T B 染色可将其染成蓝色,而具有完整细胞膜的活细胞会排斥染料,因而在生物学实验中,T B 也常用于区分正常细胞与死亡细胞㊂但是有文献[7]证实,经过5m i n 染色,T B 就会对细胞产生毒性,5~30m i n 染色会导致T B 染料渗透健康细胞的细胞膜,细胞会随着时间的推移而死亡,最终健康细胞也会被T B 染色,因而使用T B 进行细胞染色的最终结果是降低细胞活性[8]㊂本文成功制备了一种荧光素(f l u o r e s c e i n ,F N )与U i O -66的复合材料F N@U i O -66,表征了其结构并研究了其在水溶液中对T B 的荧光检测性能㊂实验研究表明,F N@U i O -66对T B 具有良好的选择性和灵敏度,可用于荧光检测T B ㊂1 材料与方法1.1 试剂与仪器四氯化锆㊁荧光素(F N )㊁曲利苯蓝(T B )㊁对苯二甲酸(H 2B D C )㊁N ,N -二甲基甲酰胺(D M F )㊁盐酸㊁甲醇㊁冰乙酸㊁醋酸钠㊁乙腈㊁乙酸乙酯㊁三氯甲烷㊁二甲基亚砜(D M S O )等试剂均为分析纯或更高纯度,实验中未进行纯化而直接使用;实验用水为超纯水(18.2MΩ㊃c m )㊂采用日本日立公司的S U 8010型扫描电子显微镜(s c a n n i n g e l e c t r o n m i c r o s c o p e ,S E M )对样品的表面形貌特征进行检测,工作距离为3.8mm ,加速电压为3.0k V ;采用日本理学公司的X 射线粉末衍射仪测定样品的X 射线衍射(X -r a y d i f f r a c t i o n ,X R D )图谱,铜靶K α线波长为0.15405n m ,扫描速度为10ʎ㊃m i n -1,扫描范围为5ʎ~50ʎ,管电压为40k V ,管电流为40m A ;采用英国马尔文公司的N a n o -Z S 90型纳米粒度分析仪测试样品的平均粒度;采用美国赛默飞公司的N i c o l e t i S5型傅里叶变换红外光谱仪测试样品的红外光谱;采用美国瓦里安公司的C a r y E c l i p s e 型荧光光谱仪对悬浮液样品进行荧光测试㊂1.2 F N @U i O -66的制备F N@U i O -66的合成方法参照文献[9]㊂首先准确称取0.4514g Z r C l 4,0.3289g H 2B D C ,0.0338g F N ,34.0m LD M F 和0.34m LH C l 于250m L 烧杯中,混合搅拌1h 后使全部反应物完全溶解在D M F 中,得到均匀的反应液㊂随后将反应液转移至装有50m L 聚四氟乙烯内衬的不锈钢反应釜中,在120ħ烘箱中连续加热24h ,待其自然冷却后,将得到的黄色粉末用D M F 和甲醇溶液洗涤4次并抽滤,得到粗产物㊂将粗产物在80ħ下烘干12h 后,自然冷却并研磨,得到黄色固体粉末,即为F N@U i O -66㊂1.3 荧光实验将F N@U i O -66粉末(30m g)加入30m L 超纯水中,室温下静置24h ,然后将此样品进行30m i n 超声处理后得到稳定的悬浮液㊂分别准确移取多份2.5m L 的悬浮液,加入不同体积的5ˑ10-4m o l ㊃L -1T B 水溶液,并测试其光致发光(ph o t o l u m i n e s c e n c e ,P L )谱图㊂进行重复性实验时,将F N@U i O -66粉末从悬浮液中高速离心出,经无水乙醇充分洗涤后晾干即可重复使用㊂2 结果与讨论2.1 F N @U i O -66的表征图1分别给出了文献[10]报道的U i O -66单晶数据模拟㊁本文合成的F N@U i O -66及在T B 溶液984第6期 刘丽艳,等:荧光素@U i O -66金属有机框架材料荧光检测曲利苯蓝图1 U i O -66单晶模拟㊁F N @U i O -66及在T B

N @U i O -66中浸泡24h 后的F N@U i O -66的X R D 谱图㊂由图1可以看出,U i O -66在2θ为7.36ʎ和8.50ʎ处有明显的特征衍射峰,在14.76ʎ,17.06ʎ,25.72ʎ,30.72ʎ等处也有相对较强的衍射峰㊂本文合成的F N@U i O -66材料衍射峰与单晶数据模拟的U i O -66特征峰峰位相同且强度较高,未出现其他杂峰,这表明已经成功获得F N@U i O -66材料,并且其纯度和结晶度良好㊂当F N@U i O -66在T B 溶液中浸泡24h 后,其峰位和峰强并没有发生变化,也没有出现明显的杂峰,表明在荧光检测T B过程中,F N@U i O -66材料结构稳固,没有发生变化㊂图2给出30000倍和60000倍放大倍率下的F N@U i O -66样品的S E M 照片㊂可以看出,F N@U i O -66样品晶化程度良好,晶体颗粒大小均匀,晶粒呈正四面体,粒径范围约为150~300n m ,与文献[10]报道相一致,表明成功地合成出F N@U i O -66样品,样品纯度比较高,并且F N 的引入并不会导致U i O -66的结构发生变化㊂(a )放大倍率30000倍(b )放大倍率60000倍图2 F N @U i O -66的S E M 照片F i g .2 S E Mi m a ge

-66复合材料的成功合成㊂图3 (a )U i O -66与(b )F N @U i O -66的粒径分布图F i g .3 A v e r a ge p a r t i c l es i z ed i s t r i b u t i o n p l o t of (a )U i O -66a n d (b )F N @U i O -66图4为U i O -66,F N 与F N@U i O -66的红外光谱图㊂如图4(a )所示,3430c m -1处的宽峰可归属为O H 键伸缩振动,1398c m -1处强吸收峰可归属为配体中羧基伸缩振动,1505c m -1和1583c m -1094沈阳师范大学学报(自然科学版) 第41卷图4 (a )U i O -66,(b )F N ,(c )F N @U i O -66的红外光谱图F i g .4 I Rs pe c t r aof (a )U i O -66,(b )F Na n d (c )F N @U i O -66处的特征峰是配体分子中苯环的骨架振动引起的,550c m -1处的吸收峰对应Z r O C 键,这个吸收峰的存在证明了金属有机框架结构的建立,表明成功地合成了U i O -66㊂图4(c )给出F N@U i O -66材料的红外光谱图,由图4(c )可见,复合F N 后U i O -66的红外谱图变化不明显,一些强吸收峰出现几个波数的红移,例如,1398c m -1处吸收峰红移至1401c m -1处,1583c m -1处吸收峰红移至1584c m -1处,但并未出现F N 如1598c m -1,1112c m -1处的特征吸收峰,推测其原因可能是U i O -66中复合的F N 量较少㊂由图5(a )可以看出,U i O -66及F N@U i O -66的氮气吸附脱附等温曲线均呈现典型的Ⅰ类吸附等温线特点,即在P /P 0比较低时吸附量快速上升,随着P /P 0的增加,吸附量达到一个饱和值,当接近饱和压力(P /P 0接近1.0)时,曲线上扬㊂这表明U i O -66及F N@U i O -66都是典型的微孔结构㊂复合F N 后,U i O -66的氮气吸附量明显下降,比表面积由1005.3452m 2㊃g -1下降至873.5886m 2㊃g -1,这也从另一方面证明了F N@U i O -66的成功合成㊂图5(b )给出U i O -66及F N@U i O -66的孔分布情况,复合F N 后U i O -66的孔体积显著减小,只有0.86n m 大小的孔体积变大,本文推测这可能是复合F N后,U i O -66表面部分孔的孔径发生改变所致㊂(a )(b)图5 U i O -66与F N @U i O -66的(a

m 处峰外,在523n m 处存在强度更大的发射峰,此峰对应于F N 分子的特征发射㊂2.2 F N @U i O -66对T B 的荧光检测图7(a )为不同浓度T B 存在下F N@U i O -66悬浊液的发光情况㊂可以看出,随着T B 浓度的增加,体系的发光强度逐渐降低,发生荧光猝灭现象,并且主发射峰发生蓝移,由523n m 变为520n m ,表明T B 的194第6期 刘丽艳,等:荧光素@U i O -66金属有机框架材料荧光检测曲利苯蓝引入降低了体系F N 分子周围的极性,增加了环境的疏水性㊂一般来说,荧光猝灭包括静态猝灭和动态猝灭,可使用S t e r n -V o l m e r 方程(式(1))分析㊂F 0F=1+K S V [Q ](1)其中:F 与F 0分别为有无猝灭剂时体系的荧光发射强度;[Q ]是猝灭剂浓度;K S V 是S t e r n -V

共振能量传递理论[14],当荧光体与物质距离较近时,如果荧光体的发射光谱与物质的吸收光谱之间存在重叠,二者之间会发生能量传递,这是引起荧光猝灭的原因之一㊂图8给出了室温下F N@U i O -66荧光发射光谱与T B 紫外可见光谱的重叠谱图㊂由图8可见,二者之间存在较大程度的重叠,导致F N@U i O -66荧光发射能量向T B 转移,F N@U i O

Trigonox 311 3,3,5,7,7-Pentamethyl-1,2,4-trioxepan

Product Data SheetTrigonox 3113,3,5,7,7-Pentamethyl-1,2,4-trioxepaneTrigonox® 311 is a pure peroxide in liquid form.CAS number215877-64-8EINECS/ELINCS No. 455-560-2TSCA statuslisted on inventory Molecular weight 174.24Active oxygen content peroxide9.18%Concentration 8.72% min.SpecificationsAppearance Clear liquidAssay≥ 95.0 %ApplicationsTrigonox® 311 is a monofunctional peroxide which is used for the crosslinking of natural rubber and synthetic rubbers, as well as polyolefins. Safe processing temperature: 180°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 220°C (rheometer t90 about 12 min.).Thermal stabilityOrganic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT120°C (248°F)Method The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria - United Nations, NewYork and Geneva).StorageDue to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperatureTs Max.40°C (104°F)Ts Min.15°C (59°F) to prevent crystallizationNote When stored under these recommended storage conditions, Trigonox® 311 willremain within the Nouryon specifications for a period of at least 12 months afterdelivery.Packaging and transportThe standard packaging is a 30-liter HDPE can (Nourytainer®) for 25 kg peroxide solution. Both packaging and transport meet the international regulations. For the availability of other packed quantities contact your Nouryon representative. Trigonox® 311 is classified as Organic peroxide type E; liquid, Division 5. 2; UN 3107.Safety and handlingKeep containers tightly closed. Store and handle Trigonox® 311 in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g. amines), acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of Trigonox® 311.

WHO International Standard 1st WHO International Standard for Human Papillomavirus (HPV) Type 16 DNA

WHO International Standard 1st WHO International Standard for Human Papillomavirus (HPV) Type 16 DNA

WHO International Standard1st WHO International Standard for Human Papillomavirus (HPV)Type 16 DNA NIBSC code: 06/202 Instructions for use(Version 2.0, Dated 10/11/2010)1. INTENDED USEThe 1st International Standard for HPV Type 16 (HPV-16) DNA Nucleic Acid Amplification Techniques consists of a freeze-dried preparation of recombinant plasmid containing full-length HPV-16 DNA cloned via its unique BamH1 site (Quint et al., 2006). The standard has been formulated in a background of purified human genomic DNA, lyophilized in 0.5 ml aliquots and stored at -20 °C. The material was calibrated in an international collaborative study involving 19 laboratories (Wilkinson et al., 2008). The International Standard contains material that is proprietory to third parties and should be used for the sole purpose of calibrating in-house or working standards for the amplification and detection of HPV-16 DNA. The International Standard should not be used for any other purpose and should be discarded after use. 2. CAUTIONThis preparation is not for administration to humans .This material contains DNA derived from C33A cells. As with all materials of biological origin, this preparation should be regarded as potentially hazardous to health. It should be used and discarded according to your own laboratory's safety procedures. Such safety procedures should include the wearing of protective gloves and avoiding the generation of aerosols. Care should be exercised in opening ampoules or vials, to avoid cuts.3. UNITAGEThe 1st International Standard for HPV-16 DNA Nucleic Acid Amplification Techniques has been assigned a unitage of 5 x 106 International Units (IU) per ampoule.Traceability statement:It was proposed at a WHO meeting in January 2008 (WHO Meeting Report, 2008) that the instructions for use of the International Standard for HPV-16 DNA include the calculations and assumptions used in determining the theoretical HPV-16 qenome equivalents (GEq) of the bulk material used in formulating the International Standard, thus demonstrating that 1 IU is equivalent to 1 GEq for HPV-16 DNA . The definitive unitage of the 1st WHO International Standard for HPV-16 DNA therefore remains as IU while the traceability statement would allow users to equate IU with GEq.Assays for DNA concentration of the recombinant HPV-16 plasmid stock preparation were performed in Dr Cosette Wheeler‟s laboratory, University of New Mexico (UNM). DNA concentrations were determined by absorbance at 260 nm as well as spectrofluorometrically using the Picogreen assay (Invitrogen Corporation, USA). A correlation coefficient of 0.95 or higher was obtained between the two DNA measurements. 10 ng HPV-16 plasmid DNA/μl was supplied to NIBSC for formulating the bulk material for subsequent freeze-drying. The UNM laboratory also provided NIBSC with a statement indicating that 1.0 x 1011 GEq/ml for HPV-16 is equal to 1.17 ng/μl. 10 ng HPV-16 plasmid DNA/μl plasmid stock preparation is therefore equivalent to 8.547 x 1011 HPV-16 GEq/ml. NIBSC used this data in formulating the 1st International Standard for HPV Type 16 DNA.Formulation of bulk material for the 1st International Standard for HPV Type 16 DNA (NIBSC code 06/202):At NIBSC, the bulk HPV-16 plasmid DNA material was prepared according to the formula:HPV GEq/ml of bulk material = (HPV GEq/ml of plasmid stock x volume plasmid stock) / volume bulk material.Therefore,HPV-16 GEq/ml of bulk material = (8.547 x 1011 HPV-16 GEq/ml plasmid stock) x (0.02223 ml HPV-16 plasmid stock) / 1900 ml HPV-16 bulk material = 1.0 x 107 HPV-16 GEq/ml bulk materialThe HPV-16 DNA bulk material was subsequently freeze-dried in 0.5 ml aliquots.Certain assumptions are required for equating IU to GEq for the 1st International Standard for HPV-16 DNA: 1) 1.0 x 1011 GEq/ml for HPV-16 is equal to 1.17 ng/μl. 2) There is no loss in activity of the HPV-16 DNA upon lyophilization. 3) The recombinant HPV-16 plasmid DNA accurately mimics the activity of HPV-16 viral DNA in biological samples.Independent calculation of GEq/ml for recombinant HPV-16 plasmid DNA.NIBSC also independently calculated the genome equivalence of the HPV-16 plasmid stock preparation and bulk preparation in which the molecular weights of the full-length HPV-16 genome and pBR322 DNA were based on sequence content using BioEdit Sequence Alignment Editor v7.0.5.3 (Tom Hall, Isis Pharmaceuticals Inc., USA). The sequences used for determining the molecular weights are GenBank Accession number J01749.1 for pBR322 and the reference sequence for HPV16 (Accession K02718).BioEdit dataDNA molecule: HPV16 Accession K02718 Length = 7904 base pairsMW= 4786756.00 Daltons, double strandedDNA molecule: cloning vector pBR322 Length = 4361 base pairsMW= 2653867.00 Daltons, double strandedFormulaeGEq/ml of the HPV plasmid stock was calculated according to the formula: GEq/ml of the HPV plasmid stock = (DNA concentration of HPV plasmid stock) x (MW of HPV DNA + MW of pBR322)-1 x (Avogadro‟s Number) where Avogadro‟s Number = 6.022x1023 molecules/molGEq/ml of the bulk HPV DNA materials was calculated according to the formula:HPV GEq/ml of bulk material = (HPV GEq/ml of plasmid stock x volume plasmid stock) / volume bulk material.CalculationThe recombinant HPV-16 plasmid stock preparation was supplied to NIBSC at a concentration of 10 ng/μl. Using the MW determinations shown above, the GEq/ml of the HPV-16 plasmid stock is:= (10 x 10-9 g/μl) x (mol/(7440623 g) x (6.022x1023 molecules/mol) = 8.093 x 108 molecules/μl = 8.093 x 1011molecules/ml = 8.093 x 1011 HPV-16 GEq/ml22.23μl of the recombinant HPV-16 plasmid stock was diluted to a final volume of 1900ml, therefore,HPV-16 GEq/ml of bulk material = (8.093 x 1011 HPV-16 GEq/ml plasmid stock) x (0.02223 ml HPV-16 plasmid stock) / 1900 ml HPV-16 bulk material = 0.947 x 107 HPV-16 GEq/ml bulk material4. CONTENTSCountry of origin of biological material: United Kingdom.Each ampoule contains the lyophilized equivalent of 0.5 ml HPV-16 plasmid DNA in 10mM Tris buffer pH7.4 containing 1mM EDTA, 5 mg/ml trehalose and ~1 x 106 human GEq/ml derived from C33a cells.5. STORAGEThe ampoule should be stored at -20 °C or below on receipt.Please note: because of the inherent stability of lyophilized material, NIBSC may ship these materials at ambient temperature.6. DIRECTIONS FOR OPENINGDIN ampoules have an …easy -open‟ coloured stress point, where the narrow ampoule stem joins the wider ampoule body.Tap the ampoule gently to collect the material at the bottom (labeled) end. Ensure that the disposable ampoule safety breaker provided is pushed down on the stem of the ampoule and against the shoulder of the ampoule body. Hold the body of the ampoule in one hand and the disposable ampoule breaker covering the ampoule stem between the thumb and first finger of the other hand. Apply a bending force to open the ampoule at the coloured stress point, primarily using the hand holding the plastic collar.Care should be taken to avoid cuts and projectile glass fragments that might enter the eyes, for example, by the use of suitable gloves and an eye shield. Take care that no material is lost from the ampoule and no glass falls into the ampoule. Within the ampoule is dry nitrogen gas at slightly less than atmospheric pressure. A new disposable ampoule breaker is provided with each DIN ampoule.7. USE OF MATERIALNo attempt should be made to weigh out any portion of the freeze-dried material prior to reconstitution.The 1st International Standard for HPV-16 DNA contains high copy number template. There is a high risk of HPV-16 plasmid DNA contamination via aerosolization upon opening of the glass ampoule. The material must be opened and handled in a separate laboratory environment, away from other pre-amplification components such as reagents, labware and samples.The material is supplied lyophilized and, before use, should be reconstituted in 0.5 ml sterile nuclease-free water. Ensure that the inside surface of the ampoule is wetted with the added water so that any particles of freeze-dried material adhering to the glass are reconstituted. The reconstituted material has a final concentration of 1 X 107 IU/ml. The reconstituted material is suitable for calibration of in-house or working standards for the amplification and detection of HPV-16 DNA.. The material is not suitable for calibrating or assessing extraction, precipitation or centrifugation procedures. The material has NOT been calibrated for human DNA nucleic acid amplification techniques.8. STABILITYReference materials are held at NIBSC within assured, temperature-controlled storage facilities. The 1st International Standard for HPV-16 DNA should be stored at -20 °C or below on receipt.Studies on the stability of reconstituted standard are underway. Users should determine the stability of the reconstituted material according to their own method of preparation, storage and use.NIBSC follows the policy of WHO with respect to its reference materials.9.

Product Information Presentation, Storage and StabilityThe Incucyte® Fabfluor-pH Antibody Labeling Reagents for antibody internalization are supplied as lyophilized solids in sufficient quantity to label 50 μg of test antibody, when used at the suggested molar ratio (1:3 of test antibody to labeling Fab). The lyophilized solid can be stored at 2-8° C for one year. Once re-hydrated, any unused reagent should be aliquoted and stored at -80° C for up to one year. Avoid repeated freeze-thaw cycles.Incucyte® Fabfluor-pH Antibody Labeling ReagentsFor Antibody Internalization AssaysAntibody Labeling Reagent Rehydrated: -80° C *Excitation and Emission maxima were determined at a pH of 4.5.Fabfluor_quick_guideBackgroundIncucyte ® Fabfluor-pH Antibody Labeling Reagents are designed for quick, easy labeling of Fc-containing test antibodies with a Fab fragment-conjugated pH-sensitive fluorophore. The pH-sensitive dye based system exploits the acidic environment of the lysosomes to quantify in-ternalization of the labeled antibody. As Fabfluor labeled antibodies reside in the neutral extracellular solution (pH 7.4), they interact with cell surface specific antigens and are internalized. Once in the lysosomes, they enter an acidic environment (pH 4.5–5.5) and a substantial in-crease in fluorescence is observed. In the absence of ex-pression of the specific antigen, no internalization occurs and the fluorescence intensity of the labeled antibodies remains low. With the Incucyte ® integrated analysis soft-ware, background fluorescence is minimized. These reagents have been validated for use with a number of different antibodies in a range of cell types. The Incucyte ® Live-Cell Analysis System enables real-time, kinetic eval -uation of antibody internalization.Recommended UseWe recommend that the Incucyte ® Fabfluor-pH Antibody Labeling Reagents are prepared at a stock concentration of 0.5 mg/mL by the addition of 100 μL of sterile water and triturated (centrifuge if solution not clear). The reagent may then be diluted directly into the labeling mixture with test antibody. Do NOT sonicate the solution.Additional InformationThe Fab antibody was purified from antisera by a combination of papain digestion and immunoaffinity chromatography using antigens coupled to agarose beads. Fc fragments and whole IgG molecules have been removed.Human Red (Cat. No. 4722) or Human Orange (Cat. No. 4812)—Based on immunoelectrophoresis and/ or ELISA, the antibody reacts with the Fc portion of human IgG heavy chain but not the Fab portion of human IgG. No antibody was detected against human IgM, IgA or against non-immunoglobulin serum proteins. The anti-body may cross-react with other immunoglobulins from other species.Mouse IgG1 (Cat. No. 4723), IgG2a (Cat. No. 4750) or IgG2b (Cat. No. 4751)—Based on antigen-binding assay and/or ELISA, the antibody reacts with the Fc portion of mouse IgG, IgG2a or IgG2b, respectively, but not the Fab portion of mouse immunoglobulins. No antibody was detected against mouse IgM or against non–immunoglobulin serum proteins. The antibody may cross-react with other mouse IgG subclasses or with immunoglobulins from other species.Rat (Cat. No. 4737)—Based on immunoelectrophoresis and/or ELISA, the antibody reacts with the Fc portion of rat IgG heavy chain but not the Fab portion of rat IgG. No antibody was detected against rat IgM, IgA or against non-immunoglobulin serum proteins. The antibody may cross-react with other immunoglobulins from other species.A.B.C.D.R e d O b j e c t A r e a (x 105 μm 2 p e r w e l l )Time (hours)A U C x 106 (0–12 h )log [α–CD71] (g/mL)Example DataFigure 1: Concentration-dependent increase in antibody internalization of Incucyte ® Fabfluor labeled-α-CD71 in HT1080 cells. α-CD71 and mouse IgG1 isotype control were labeled with Incucyte ® Mouse IgG1 Fabfluor-pH Red Antibody Labeling Reagent.

Seed target cells of interest1.1 Harvest cells of interest and determine cell concentra-tion (e.g. trypan blue + hemocytometer).1.2 Prepare cell seeding stock in target cell growth mediawith a cell density to achieve 40–50% confluence be-fore the addition of labeled antibodies. The suggested starting range is 5,000–30,000 cells/well, although the seeding density will need to be optimized for each cell type.Note: For non-adherent cell types, a well coating may be required to maintain even cell distribution in the well. For a 96-well flat bottom plate, we recommend coating with 50 μL of either 0.01% Poly-L-Or-nithine (PLO) solution or 5 μg/mL fibronectin diluted in 0.1% BSA.Coat plates for 1 hour at ambient temperature, remove solution from wells and then allow the plates to dry for 30-60 minutes prior to cell addition.1.3 Using a multi-channel pipette, seed cells (50 µL perwell) into a 96-well flat bottom microplate. Lightly tapplate side to ensure even liquid distribution in well. Toensure uniform distribution of cells in each well, allowthe covered plate sit on a level surface undisturbed at room temperature in the tissue culture hood for 30minutes. After cells are settled, place the plate insidethe Incucyte® Live-Cell Analysis System to monitor cell confluence.Note: Depending on cell type, plates can be used in assay once cells have adhered to plastic and achieved normal cell morphology e.g.2-3 hours for HT1080 or 1-2 hours for non-adherent cell types. Some cell types may require overnight incubation.2. Label Test Antibody2.1 Rehydrate the Incucyte® Fabfluor-pH Antibody Label-ing Reagent with 100 µL sterile water to result in a final concentration of 0.5 mg/mL. Triturate to mix (centrifuge if solution is not clear).Note: The reagent is light sensitive and should be protected fromlight. Rehydrated reagent can be aliquoted into amber or foilwrapped tubes and stored at -80° C for up to 1 year (avoid freezing and thawing).2.2 Mix test antibody with rehydrated Incucyte® Fabfluor–pH Antibody Labeling Reagent and target cell growth media in a black round bottom microplate or ambertube to protect from light (50 µL/well).a. Add test antibody and Incucyte® Fabfluor–pH Anti-body Labeling Reagent at 2X the final concentration.We suggest optimizing the assay by starting with afinal concentration of 4 µg/mL of test antibody or theFabfluor-pH Antibody Labeling Reagent (i.e. 2Xworking concentration = 8 µg/mL).Note: A 1:3 molar ratio of test antibody to Incucyte® Fabfluor-pHAntibody Labeling Reagent is recommended. The labeling re-agent is a third of the size of a standard antibody (50 and 150KDa, respectively). Therefore, labeling equal quantities will pro-duce a 1:3 molar ratio of test antibody to labeling Fab.b. Make sufficient volume of 2X labeling solution for50 µL/well for each sample. Triturate to mix.c. Incubate at 37° C for 15 minutes protected from light.Note: If performing a range of concentrations of test antibody,e.g. concentration response-curve, it is recommended to createthe dilution series post the conjugation step to ensure consistentmolar ratio. We strongly recommend the use of both a negativeand positive control antibody in the same plate.3. Add labeled antibody to cells3.1 Remove cell plate from incubator.3.2 Using a multi-channel pipette, add 50 µL of 2X labeledantibody and control solutions to designated wells.Remove any bubbles and immediately place plate in the Incucyte® Live-Cell Analysis System and start scanning.Note: To reduce the risk of condensation formation on the lid priorto first image acquisition, maintain all reagents at 37° C prior toplate addition.4. Acquire images and analyze4.1 In the Incucyte® Software, schedule to image every15-30 minutes, depending on the speed of the specific antibody internalization.a Scan on schedule, standard. If the Incucyte® Cell-by-Cell Analysis Software Module (Cat. No. 9600-0031)is available, adherent cell-by-cell or non-adherentcell-by-cell scan types can be selected.b Channel selection: select “phase” and “red” or“phase” and "orange” (depending on reagent used).c Objective: 10X or 20X depending on cell types used,generally 10X is recommended for adherent cells,and 20X for non-adherent or smaller cells.NOTE: The optional Incucyte® Cell-by-Cell Analysis SoftwareModule enables the classification of cells into sub-populationsbased on properties including fluorescence intensity, size andshape. For further details on this analysis module and its appli-cation, please see: /cell-by-cell.4.2 To generate the metrics, user must create an AnalysisDefinition suited to the cell type, assay conditions andmagnification selected.4.3 Select images from a well containing a positiveinternalization signal and an isotype control well(negative signal) at a time point where internalizationis visible.4.4 In the Analysis Definition:Basic Analyzer:a. Set up the mask for the phase confluence measurewith fluorescence channel turned off.b. Once the phase mask is determined, turn the fluores-cence channel on: Exclude background fluorescencefrom the mask using the background subtractionfeature. The feature “Top-Hat” will subtract localbackground from brightly fluorescent objects withina given radius; this is a useful tool for analyzing ob-jects which change in fluorescence intensity overtime.i The radius chosen should reflect the size of thefluorescent object but contain enough backgroundto reliably estimate background fluorescence inthe image; 20-30 μm is often a useful startingpoint.ii The threshold chosen will ensure that objectsbelow a fluorescence threshold will not bemasked.iii Choose a threshold in which red or orange objectsare masked in the positive response image but lownumbers in the isotype control, negative responsewell. For a very sensitive measurement, for example,if interested in early responses, we suggest athreshold of 0.2.NOTE: The Adaptive feature can be used for analysis but maynot be as sensitive and may miss early responses. If interestedin rate of response, Top-Hat may be preferable.Cell-by-Cell (if available):a. Create a Cell-by-Cell mask following the softwaremanual.b. There is no need to separate phase and fluorescencemasks. The default setting of Top-Hat No Mask forthe fluorescence channel will enable backgroundsubtraction without generation of a mask. Ensurethat the Top-Hat radius is set to a value higher thanthe radius of the larger clusters to avoid excess back-ground subtraction.c. The threshold of fluorescence can be determined inCell-by-Cell Classification.Specifications subject to change without notice.© 2020. All rights reserved.

BSI-201_DataSheet_MedChemExpress

Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:BSI–201 (Iniparib; NSC–746045) is a PARP1 inhibitor with demonstrated effectiveness in triple–negative breast cancer (TNBC).IC50 Value:Target:PARP1in vitro: BSI–201 inhibits the growth of E–ras 20 cells, the effect of which can be augmented 4–fold when BOS is added. RecentlyBSI–201 shows no ability to inhibit PARP enzymatic or cellular activity, but can non–selectively modify cysteine–containing proteins in tumor cells, suggesting the mechanism of action for BSI–201 is likely not via inhibition of PARP activity. BSI–201 (100 μM) inhibits ionizing radiation–induced single–strand breaks (SSBs) repair in human lymphoid cell lines based on large endogenous Epstein–Barr virus (EBV) circular episomes assay, resulting in 55% repair by 2 hours, which can be reversed surprisingly by knockdown of PARP1,indicating that the mechanism of inhibition does not involve trapping PARP at SSBs. BSI–201 is not able to selectively kill homologous recombination (HR)–deficient cells between BRCA2–deficient PEO1 and BRCA2–revertant PEO4, or ATM–deficient GM16666 and ATM–restored GM16667 fibroblasts. BSI–201 is cytotoxic to a variety of cell lines at concentrations above 40 μM reflecting a mechanism independent of PARP.PROTOCOL (Extracted from published papers and Only for reference)Cell assay [5]Cells plated at 5 × 104 cells/60 mm dish were allowed to adhere for 24 h, then treated with veliparib, olaparib, or Iniparib in 0.1% (v/v)DMSO for 4 days (olaparib) or 6 days (veliparib, Iniparib) based on preliminary time course experiments. At the end of treatment,adherent cells were recovered by trypsinization, combined with cells in the supernatant, sedimented at 150 × g for 10 min, washed in ice–cold calcium– and magnesium–free Dulbecco's phosphate–buffered saline (PBS), and fixed at 4°C by drop–wise addition ofethanol to a final concentration of 50% (v/v). Cells were subsequently rehydrated in cold PBS, sedimented, resuspended in 300 μl 0.1%(w/v) sodium citrate containing 1 mg/ml RNase A, incubated for 15 min at 37°C, diluted with 300 μl 0.1% sodium citrate containing 100 μg/ml PI, incubated in the dark at 20°C for 15 min, and analyzed (20,000 events) on a FACSCanto II flow cytometer using excitation and emission wavelengths of 488 and 617 nm, respectively. After data were analyzed using Becton Dickinson CellQuest software, normalized apoptosis was calculated as (observed – baseline)/(100 – baseline) to correct for differences in basal apoptosis rates between cell lines. Results are representative of at least 3 independent experiments.References:[1].

2019年多粘菌素最佳使用方法的国际共识指南

2019年多粘菌素最佳使用方法的国际共识指南

2019年多粘菌素最佳使用方法的国际共识指南前言本临床指南的目的在于为多粘菌素类抗生素(包括多粘菌素E和多粘菌素B)的临床应用提供专家共识和推荐意见。

多粘菌素类抗生素在上世纪50年的就已面世,因而没有经历过现代药物开发应该经历的流程。

多粘菌素的独特作用机制在于它可破坏革兰阴性杆菌的外膜的完整性,除此之外还具有快速的杀菌活性,并和其他类抗生素具有协同作用。

它们的临床价值在近些年又重新被予以重视,并认为在其他药物治疗无效的革兰阴性杆菌感染的挽救性治疗方案中扮演了关键的角色,主要针对多重耐药细菌(MDR)和泛耐药细菌(XDR)如:假单胞菌属、鲍曼不动杆菌、肠杆菌属。

从1980年代开始重新进入到临床,直到现在,由于剂型的问题,多粘菌素的使用一直存在着相当的困惑。

粘菌素本身为一种不具备活性的前体药物,然而多粘菌素B则具有药物活性。

除此之外,多粘菌素类药物的剂量也存在多种不同的使用习惯,尤其是粘菌素,产品信息已经过时,而且其敏感性的测试仍存在不确定性。

因此,粘菌素和多粘菌素B最佳使用方法仍不太清楚。

不幸的是,多粘菌素存在严重的肾毒性,传统的使用方法容易诱发AKI。

鉴于目前多粘菌素治疗窗较窄(低治疗指数),因此本篇指南将为临床工作者提供使用多粘菌治疗多重耐药或泛耐药的革兰阴性杆菌造成的感染的实践框架。

方法共识指定组成人员包含各国际专家,他们代表的组织包括美国临床药学院(ACCP),欧洲临床微生物学及感染性疾病学会(ESCMID),美国感染病学会(IDSA),国际抗感染病药理学会(ISAP),美国重症医学会(SCCM)和感染性疾病药剂师协会(SIDP)。

评价过程是根据建议评价的等级划分进行开发和评估(GRADE),部分话题由于涉及非临床证据,无法采用GRADE分级。

临床问题和推荐意见敏感性和药代动力学/药效学1.如何测定敏感性和指导多粘菌素治疗的最小抑菌浓度(MIC)的折点是多少?推荐意见1:欧洲抗菌素敏感性试验联合委员会(EUCAST)和临床及实验室标准协会(CLSI)的多粘菌素敏感性折点联合工作小组推荐使用标准的肉稀微量释法ISO-74 20776作为粘菌素MIC测定的参考方法,并在经阳离子校对的穆勒辛顿(Mueller Hinton)肉汤中完成,且必须在无添加剂(例如聚山梨醇酯-80)的普通聚苯乙烯托盘中添加硫酸盐粘菌素。

(4)力学性能测试.采用LLY-06E/PC型电子单纤维强力仪测试CASA纤维的力学强度,测试条件为隔距10 mm、速率10 mm/min、湿度50%、温度25℃,每个样品测试10次,取其平均值.(5)热性能测试.采用204F1 Phoenix ®型差示扫描量热仪测试产物熔点,测试温度范围为25~300℃,N2氛围,升温速率为10℃/min.(6)耐化学腐蚀性测试.将称重后的纯CDA纤维及CASA纤维分别浸泡在5 mol/L HCl溶液中6 h及1 mol/L NaOH溶液中1 h后,室温下重新称重,计算失重率:式中:Wi为纤维浸入溶剂之前的质量;Wc为纤维浸入溶剂之后的质量.(7)抗菌性能测试.采用接触震荡法对CASA纤维进行抗菌性测试.向灭菌后的培养液(10 g蛋白胨、10 g NaCl、5 g牛肉膏、1 000 mL去离子水)中加入一块细菌,置于恒温培养振荡器中在37℃下培养24 h.完成后对其进行稀释接种二代菌,同样条件下培养12 h,然后用纯培养液和PBS缓冲液对培养好的菌液进行稀释,并分别加入经提前灭菌处理的样品0.2 g.将其放入恒温培养振荡器中在(24±1)℃下振荡处理18~24 h,完成后对其进行梯度稀释.将100 μL稀释液和原菌液分别加入到事先配制好的琼脂固体培养基中,并用涂布器将其涂布均匀,后将其放入恒温培养箱中,在37℃下培养24~48 h,最后拍照统计菌落,每个试样重复3次,取平均值.抑菌率用公式(3)[18]计算:式中:NB和NS分别为对照组和样品组上的菌落数.2 结果与讨论2.1 纺丝溶液的流变性能图2所示为CASA1/cellulose/(DMAc/LiCl)纺丝溶液在不同温度下的表观黏度和剪切速率的关系.图2 CASA1/cellulose/(DMAc/LiCl)在不同温度下的流动曲线Fig.2Flow curves of CASA1/cellulose/(DMAc/LiCl)at different temperatures由图2可以看出:不同温度下纺丝溶液的表观黏度随着剪切速率的增大而减小,呈现出切力变稀行为,表明此溶液为非线性流体.这是由于在热运动和剪切作用下,溶液中形成的交联点处于不断拆散和重建的动态平衡中,随着剪切作用力的提高,分子链间的缠结逐渐被拉开,分子间作用力减弱,纺丝液流动性能提高,表观黏度下降.而且随着温度的升高,溶液的表观黏度也逐渐下降,尤其到40℃时,下降速度更快.这是由于温度升高,分子运动的能量增加,导致溶液自由体积增加,分子间作用力降低,从而使溶液的流动性能增强.2.2 形貌分析图3为CASA纤维的电镜图.图3 CASA纤维的SEM图Fig.3 SEM images of CASA fibers由图3可以看出,3种纤维都具有较为光滑的表面形貌,断面中则存在一些微孔,这可能是由溶剂和水的双扩散作用所引起的.相比之下,CASA3纤维断面的微孔相对较少,比较致密,这可能是由于CASA3的取代度比较高,空间位阻相对较大,减慢了溶剂和水的双扩散作用,从而断面较为致密.2.3 XRD谱图图4为CASA纤维的XRD谱图.图4 CASA纤维的XRD谱图Fig.4 XRD spectrum of CASA fibers由图4可以看出,2θ为17°处为典型的纤维素结晶峰,22.4°处的衍射峰为非晶相的弥散特征峰[19],CASA2与CASA1相比,衍射峰形状变得尖而窄,这表明山梨酰基的增加导致分子链规整性降低.然而CASA3中山梨酰基的比例大大增加,分子链规整度有所上升,此处衍射峰的变化程度略有减弱.经计算可得,CASA1、CASA2、CASA33种纤维的结晶百分数分别为16.0%、13.4%、16.6%,这也说明随着取代度增大,三者的相对结晶度呈现先下降后上升的趋势.2.4 力学性能表1所示为3种CASA纤维的力学性能.表1 CASA纤维的力学性能Tab.1 Mechanical properties of CASA fibers种类断裂强度/(cN·dtex-1)断裂伸长率/%CASA1纤维 1.62 01.75 CASA2纤维1.70 04.34 CASA3纤维 2.02 12.83由表1可知,随着CASA取代度的增大,纤维的断裂强度呈现逐渐升高的趋势.CASA3纤维的取代度为1.13,其断裂强度达到2.02 cN/dtex,断裂伸长率也有所增加,这可能是由于该条件下纤维结构的规整性较高,所以强度较大.2.5 热性能图5为CASA纤维的DSC谱图.图5 CASA纤维的DSC谱图Fig.5 DSC spectrum of CASA fibers由图5可以看出:CASA纤维具有较高的熔点,CASA1纤维的熔点在220℃附近,随着取代度的增大,CASA2纤维的熔点呈现下降的趋势,这是因为原料中山梨酰氯的加入破坏了CA分子间和分子内的氢键作用,使得熔点下降;而CASA3纤维的熔点升高,这可能是由于CASA3的取代度增大,分子中含有的山梨酰基增多,分子链规整度增大,导致其熔点升高.这一结果与XRD所显示结果一致.2.6 耐化学腐蚀性图6所示为CASA纤维的耐化学腐蚀性.酯类物质不耐酸碱的主要原因是酸的质子化作用和碱的皂化反应.由图6可以看出,纯CDA纤维在酸溶液和碱溶液中的失重率分别为28.1%和63.6%;取代度越大,CASA纤维的失重率越小,耐酸碱性越高.其中,CASA3纤维在酸和碱溶液中的失重率仅为4.5%和10.3%,这说明山梨酰基的空间屏蔽效应能有效阻止酸碱质子对酯键的攻击.CASA纤维的这一优异性能拓宽了醋酸纤维素材料的应用领域.图6 CASA纤维分别在5 mol/L HCl和1 mol/L NaOH溶液中浸泡一定时间后的失重率Fig.6 Mass loss of CASA fibers soaked in 5 mol/L HCl and 1 mol/L NaOH solutions for some times2.7 抗菌性能图7为所制备纤维经接触震荡法测试所得2种细菌菌液中残留菌落的生长分布实物图.图7 CASA纤维抗菌实验中的菌落分布Fig.7 Colony distribution in antibacterial test of CASA fibers由图7可以看出,与CDA纤维接触的琼脂培养基表面细菌生长较为明显,存在着大量菌落.相比之下,与CASA纤维接触的培养基表面菌落数明显减少.图8所示为CASA纤维对2种细菌的抑菌率.图8 CASA纤维的抑菌率Fig.8 Bacteriostatic rate of CASA fibers由图7和图8可见,随着取代度的增大,CASA纤维对大肠杆菌和金黄色葡萄球菌的抑菌率均呈现先上升后下降的趋势,最高分别达到76.5%和90.2%.这是由于随着取代度的增加,CA骨架上更多的亲水性基团羟基被疏水性物质山梨酸酯化,CASA可以自由通过细胞膜进入细胞,并与生命物质功能域发生作用,抑制酶体系,达到抑菌作用.然而,当取代度增大到1.13时,高取代度会产生一定的空间位阻效应,从而降低了反应活动中心的空间活动自由度,与微生物功能结构域的有效碰撞降低,最终影响抗菌活性的发挥[20].另外,同种纤维对金黄色葡萄球菌的抑制作用要高于大肠杆菌,这可能与两者的细胞壁结构差异有关[21].3 结论将醋酸纤维素和山梨酰氯在DMAc中进行接枝反应,制备出CASA,并利用干湿法纺丝技术制备出CASA纤维,对纤维性能进行分析,结果表明:(1)CASA1/cellulose/(DMAc/LiCl)纺丝溶液为切力变稀体系,体系的黏度随着剪切速率的增加以及温度的提高呈下降趋势.(2)CASA纤维具有较好的表面形貌,且具有较高的熔点.随着取代度增大,CASA纤维的断面变得更为致密,结晶度和熔点先下降后上升.(3)随着取代度的增大,CASA纤维的断裂强度逐渐增大,取代度为1.13的CASA纤维断裂强度达到2.02 cN/dtex.(4)CASA纤维具有良好的耐化学腐蚀性,取代度为1.13的CASA纤维在5mol/LHCl和1mol/L NaOH溶液中分别浸泡6 h和1 h后失重率分别为4.5%和10.3%.(5)CASA纤维具有良好的抗菌效果,取代度为0.81的CASA纤维对大肠杆菌和金黄色葡萄球菌的抑菌率分别为76.5%和90.2%.【相关文献】[1] 许冬生.纤维素衍生物[M].北京:化学工业出版社,2001.XU D S.CelluloseDerivatives[M].Beijing:Chemical Industry Press,2001(in Chinese).[2]BHATTACHARYAA,MISRABN.Grafting:Aversatilemeans to modify polymers:Techniques,factors and applications[J].Progress in Polymer Science,2004,29(8):767-814.[3]SAKAI K,YAMAUCHI T,NAKASU F,et al.Biodegradation of cellulose acetate by neisseria sicca[J].Bioscience Biotechnology&Biochemistry,1996,60(10):1617.
