自噬研究方法
MDC:取12 mg粉末溶于720 nl DMSO使其浓度为50 mmol/L,分装后-20冰箱保存。
临用前用MEM稀释到终浓度50 umol/L;Rapamycin:用MEM培养基配成终浓度为1 umol/L,现用现配;400ng/ml喹乙醇:称取4 mg喹乙醇,DMSO预溶(体积<0.1%)后加入10 ml MEM培养液至完全溶解,现用现配,避光保存;3-MA:首先用PBS溶解粉末,临用前加热至完全溶解后再加入MEM培养基至终浓度10mmol/L; PI3K抑制剂(3-MA,Wortmannin)可干扰或阻断自噬体的形成用RAPAMYCIN诱导自噬我也查过一部分文献,有用无血清的,也有用,一般培养基的,浓度从25nM到100nM都有,用的是50nM的雷帕霉素,加入一般的培养基中,目的是排除无血清所诱导出来的自噬。
文献说饥饿初期激活的是大分子自噬,在4-6小时活力达到最大,24h后以CMA途径为主Earle's balanced salts solution (EBSS) for 48 hsigma的EBSS,货号E2888,有碳酸氢钠,有酚红的,酚红到不是很必须,只是一个PH指示作用,好看些无血清诱导自噬:EBSS 诱导6个小时就可以了。
EBSS一定可以诱导出来,只是需要说明的是时间点的设置,因为从饥饿诱导开始半个小时就可能开始自噬了,一直到24小时都持续,所以应该设置不同的时间点观察这个作用。
另外一个很大的问题是,饥饿诱导的一个很大的弊端是细胞死亡,这也是我面临的问题,就是在细胞收养的时候蛋白浓度太小了。
24小时就很少了,更不要说48小时和72小时了Hank's诱导,也就是通常所说的饥饿诱导,细胞培养到对数生长期后以Hank's替代常规完全培养基,3h后就可诱导出自噬。
我用Hank's诱导了3h后电镜观察有30%细胞都有自噬这种现象,但不如国外报道的高。
核苷类药物知识
核苷类药物知识核苷类药物的综述,免费下载的,大家给好评吧!O(∩_∩)O~1. 前言核苷和脱氧核苷是由核苷碱基分别和核糖或脱氧核糖以苷键形式而构成的,它们是组成核糖核酸(RNA)和脱氧核糖核酸(DNA)的基本元件,是遗传基因的基础。
核苷和脱氧核苷系列衍生物具有多种生物活性物质,可以直接或间接地作为药物使用,在治疗多种重大的疾病方面起到极其重要的作用,国外已经研究开发出系列化药物并商品化,国内研究与开发较晚,发展前景非常广阔.1。
1 核苷类药物的合成与生产从20世纪40年代末期,国外就开始核苷及其系列药物的合成与开发。
目前世界排名前25位制药大公司都有自己的核苷衍生物生产或加工厂,并且均有持有专利的核苷类药物上市,并且从20世纪90年代起投入巨资用于基因药物的研究。
据国外有关资料预计,2003年基因药物的市场价值将超过30亿美元.在亚洲,日本是最早开发核苷类药物和基因药物的国家,如武田、住友、味之素等公司均有相关的中间体开发机构和生产基地。
另外韩国、印度在20世纪90年代初开始投入这类产品的开发与生产.中国在核苷及其衍生物方面的开发研究与生产始于20世纪90年代末期,但是核苷及其中间体品种少,部分原料依赖进口,与目前快速发展的生命科学及相关药物研究不相适应。
1。
2 核苷类药物的应用核苷与脱氧核苷系列化合物主要用于医药领域,用途广泛,而且新产品层出不穷,应用范围不断扩大.(一)抗病毒药物。
核苷类抗病毒药物品种繁多,结构多样,主要以破坏病毒转录,干扰或终止病毒核酸的合成为目的,用于抗疱疹病毒、HIV、HBV、以及流感和呼吸系统病毒等DNA和RNA病毒。
目前在这方面应用最多,而且新出现的药物主要集中于治疗上述疾病。
(二)抗肿瘤药物。
目前用于临床和正在研究的核苷类抗肿瘤药物有数十种,它们的主要作用是干扰肿瘤的DNA合成,或者影响核酸的转录过程,抑制蛋白质的合成,从而达到治疗肿瘤的效果。
(三)抗真菌类药物.具有这方面作用的核苷类化合物已经有多种用于临床应用,其中有部分产品对多种真菌具有抑制作用,而且对哺乳动物几乎无毒性。

3M Harvest RC 二次生物疗法制品说明书
3M™ Harvest RCSingle-stage chromatographic purification for recombinant protein therapeutic manufacturing2 | 3M ™Harvest RCThe first step in the recombinant biotherapeutic process is harvesting cell culture fluid containing the product. Conventional approaches for performing this unit operation utilize a combination of depth filtration, centrifugation, and membrane filtration. These technologies utilize differences in density and in size as the principles of separation. As cell culture processes are intensified to yield higher cell densities and product titers, the ability to effectively harvest the cell culture fluid with the consistency and scalability required becomes challenging.3M ™ Harvest RC is a harvest solution that utilizes fibrous anion exchange (AEX) chromatography to efficiently separate the cells, cell debris, and DNA from the harvest fluid containing the target product. Precisionquaternary ammonium (Q) functionalized polypropylene fiber, combined with a 0.2 µm PES membrane, provides scalable and predictable clarification from discovery to commercial manufacturing scale.Cells being captured by AEX fiberchromatographySimplify three stages into a single stageCell CultureClarification by Size3M ™ Harvest RCSterilizing MembraneSterilizing Membrane3M ™ Harvest RC | 3� Capsule format enables typical product recoveries of 95+%� R eplaces primary, secondary, and guard membrane clarification stages � P redictably scales from discovery to manufacturing in terms of clarification consistency and cell loading capacity � C apsules fit into laboratory to manufacturing scale workflows.� L ower total cost of manufacturing compared tocentrifugation and depth filtration � N o post-use cleaning required which means that there is no use of caustic or potentially toxic clean-in-place (CIP) agents � L ower consumption of buffer and water compared to depth filtrationIntroducing 3M ™ Harvest RC3M ™ Harvest RC is a new single-stage, single-use chromatographic clarification solution. It is the next generation in harvest and clarification technology and is designed as an efficient option to increase monoclonal antibody (mAb) yields while streamlining the upstream process by replacing the centrifuge and/or depth filtration process steps.ManufacturingDevelopmentScale-upDiscovery 3M ™ Harvest RC product family: laboratory, pilot, andproduction capsules.BC340CT15BC25BC4WP6BC16000BC1020BC23004 | 3M ™ Harvest RC3M ™ Harvest RC encapsulates innovative synthetic fibrous anion exchange (AEX)chromatography media and a 0.2 µm polyether sulfone (PES) membrane. This enables a single-stage clarification process of low to high-density cell culture (>40 million cells per mL) with high recovery, and high fidelity of soluble and insoluble contaminant separation. Cells are bound inside the media by electrostatic charge interaction with the AEXchromatographic fibers. This results in the efficient retention of large and small particulates without developing a surface cake layer. The media can also remove soluble impurities which results in cleaner effluent than centrifugation or depth filtration.� H igh mAb product recovery (Capsules: >95%; Conical Tube and Well Plate >90%)� C onsistent cell loading capacity � T urbidity reduction (<15 NTU)� D NA reduction (<500 ppb)� M inimal cell shear� 0.1 µm sterile filter protectionWell plateConical tube Laboratory scaleBefore and after using 3M ™ Harvest RC:turbidity reduction in a single stageAvailable formats:3M ™ Harvest RC | 5Performance datamAb product recovery3M ™ Harvest RC is a single stage chromatography solution that effectively clarifies Chinese Hamster Ovary (CHO) harvest cell culture fluid (HCCF) across a wide range of cell densities, packed cell volumes (PCV), and turbidities.3M Harvest RC chromatographic clarification capsulesconsistently provide >95% mAb product recovery for high cell density cultures from the laboratory to the manufacturing scale.Turbidity reduction3M Harvest RC provides consistent separation of cells, cell debris, and DNA from the target protein. Clarified cell culture fluid (CCCF) has low turbidity, typically <15 NTU. Additionally, consistently low acidified turbidity of CCCF indicates significant reduction of DNA in the clarified material. Low acidifiedCCCF turbidity is a measure of the amount of DNA present in the cell culture fluid. (Koehler et al. Biotechnology Progress. 2019;35:e2882)Scalability3M Harvest RC capsules scale linearly across laboratory, pilot, and manufacturing scales.Fibrous chromatographic clarification assures scalable performance from discovery to manufacturing scales. Performance isconsistent from laboratory capsules (BC4 and BC25), scale-up capsules (BC340 and BC1020), to production capsules (BC2300 and BC16000) within ±20% of BC25 throughput.Throughputs of 3M Harvest RC capsules are scaled by area based on packed cell volume.Figure 1A: mAb product recovery in clarification process at different packed cell volumes (N = 1 – 4)m A b P r o d u c t R e c o v e r y (%)Packed Cell Volume (%)105%4%5%6%7%8%9%10%100%95%90%85%80%75%Figure 1B: mAb product recovery in clarification process at different media surface areas (N = 1 – 3)m A b P r o d u c t R e c o v e r y (%)Media Surface Area (cm 2)105%10100100010000100000100%95%90%85%80%75%Figure 2: Turbidity Reduction by 3M ™ Harvest RC capsules (N = 3 – 6).

This results in minimal cell shear compared to conventional depth filtration processes evenat medium and high cell densities. Cell shear was evaluatedby lactate dehydrogenase (LDH) assay (Sigma-Aldrich 11644793001).Robust sterile filter protectionDue to the highly effective chromatographic reduction of soluble and insoluble contaminants, 3M Harvest RC enables efficient clarification, and is capable of effective protection of final sterilizing grade membrane filter down to 0.1 µm pore size.

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.

Enzyme/Coenzyme/ 5 x 100 ml α-oxoglutarate GTIN: 05055273200454UV METHODThis is an optimised standard method according to the concentrations recommended by the IFCC.CLINICAL SIGNIFICANCE (1,2,3,4)The aminotransferases are a group of enzymes that catalyse the inter conversions of amino acids and α-oxoacids by transfer of amino groups. AST (aspartate aminotransferase or glutamate oxaloacetatetransaminase) has been found in the cytoplasm and the mitochondria of cells that have been studied. In cases of mild tissue damage, e.g. liver, the predominant form of serum AST is that from the cytoplasm, with a smaller amount coming from the mitochondria. Severe tissue damage will result in more mitochondrial enzyme being released. Elevated levels of AST can signal myocardial infarction, hepatic disease, muscular dystrophy and organ damage.Although heart muscle is found to have the most activity of the enzyme, significant activity has also been seen in the brain, liver, gastric mucosa, adipose tissue and kidneys of humans.The IFCC has now recommended (1980) standardised procedures for AST determinations including:-1. optimization of substrate concentrations.2. Employment of Tris buffers (instead of phosphate, which has beenshown to inhibit recombination of the apoenzyme with pyridoxal phosphate).3. Pre-incubation of combined buffer and serum to allow sidereactions with NADH to occur. 4. Substrate start (α-oxoglutarate)5. Optional pyridoxal phosphate activation.This is an optimised standard method according to the recommendations of the IFCC.PRINCIPLEα-oxoglutarate reacts with L-aspartate in the presence of AST to form L-glutamate plus oxaloacetate. The indicator reaction utilises the oxaloacetate for a kinetic determination of NADH consumption.

冰冻切片神经组织金属锌改良蒂姆(Neo-TIMM)染色试剂盒
冰冻切片神经组织金属锌改良蒂姆(Neo-TIMM)染色试剂盒产品说明书(中文版)主要用途冰冻切片神经组织金属锌改良蒂姆(Neo-TIMM)染色试剂是一种旨在使用新型蒂姆硫化法银染技术,分析存档中的冰冻组织切片里神经系统中含锌神经细胞结构分布的权威而经典的技术方法。
该技术经过精心改良蒂姆(Timm)方法、成功实验证明的。
主要适用于冰冻脑组织(海马齿状回门区hilus of dentate gyrus、安蒙氏角cornu ammonis、大脑皮层、丘脑、杏仁核amygdala nuclei或外周神经组织切片,例如海马(hippocampus)中苔藓纤维区(mossy fiber region)和齿状分子层(dentate molecular layer)等含锌神经细胞体,例如锥体细胞(pyramidal cells)、齿状颗粒细胞(dentate granule cells)等检测。
广泛用于脑神经病理生理,尤其是退行性神经病变包括癫痫、自闭症、精神分裂症、脑损伤、脑缺血等疾病的研究。
产品严格无菌,即到即用,操作简捷,性能稳定,显色清晰。
技术背景蒂姆硫化法银染(Timm’s sulfide silver staining)是由蒂姆建立的用于观察脑组织和其它组织中(例如胰腺、小肠、睾丸、肾脏等)微量金属元素锌,以及其它重金属元素,例如铜、镍、钴和铁等的染色技术。
主要用于观察中枢神经系统中含锌神经元,以及新轴突分枝(sprouted axon)和轴突终端(axon terminal)等结构,分析大脑灰质内部的海马中轴突终端(突触泡囊synaptic vesicle)、苔藓终端(齿状颗粒细胞dentate granule cells)中的反应性锌的分布,与突触活性和膜去极化的关系,研究神经退行性和癫痫病理性变化机制。
其原理在于使用硫化物,与组织中的游离金属元素反应成为不溶性复合物沉积,进而在还原剂的作用下,金属硫化物催化还原离子银为可见金属银沉积,呈现黑色,此为金属自显影术(autometallography,AMG)。

Solubility:
DMSO 20 mg/mL; Water <1 mg/mL
Mechanisms: Pathways:Membrane Tranporter/Ion Channel; Target:Sodium Channel g y Biological Activity: Triamterene blocks epithelial Na+ channel (ENaC) in a voltage-dependent manner, which used as a mild diuretic. Target: Sodium Channel Triamterene blocked rENaC in a voltage-dependent manner, and was 100-fold less potent than amiloride at pH 7.5. At -90 mV and -40 mV, the IC50 values were 5 microM and 10 microM, respectively. The blockage by triamterene, which is a weak base with a pKa of 6.2, was dependent on the extracellular pH. The IC50 was 1 microM at pH 6.5 and only 17 microM at pH 8.5 [1]. Triamterene ( (TA) ) is partly p y eliminated by y a first-pass-effect. p The main metabolite of TA is OH-TAester, which is pharmacologically active [2]. ... References: [1].
