碧云天细胞自噬染色检测试剂盒(MDC法)说明书

碧云天细胞自噬染色检测试剂盒(MDC法)说明书

细胞自噬染色检测试剂盒(MDC 法)产品简介:碧云天生产的细胞自噬染色检测试剂盒(MDC 法),即Autophagy Staining Assay Kit with MDC ,是一种使用丹酰尸胺,也称单丹磺酰尸胺、丹酰尸胺或丹酰戊二胺(monodansylcadaverine, MDC)作为荧光探针快速便捷地检测细胞自噬的试剂盒。

自噬(autophagy)是一种在进化上高度保守的通过溶酶体吞噬并降解部分自身组分的细胞内分解代谢途径。

自噬与多种生理功能有关,在饥饿等环境条件下,细胞通过自噬降解多余或异常的细胞内组分,为细胞的生存提供能量及原材料,促进生物体的生长发育、细胞分化及对环境变化产生应答。

自噬异常与多种病理过程如肿瘤、神经退行性疾病、代谢疾病、病原体感染等都有密切关系。

由于细胞自噬在生理和病理过程中都有重要作用,自噬已经成为细胞生物学领域的一个研究热点。

MDC 是细胞自噬检测最常用的荧光探针之一。

MDC 可以通过离子捕获(ion trapping)和与膜脂的特异性结合,从而特异性标记自噬体(autophagosome),也称autophagic vacuole ,因而常用于细胞自噬的检测。

MDC 是一种嗜酸性荧光探针,很多酸性膜性结构也会被MDC 染色,因此MDC 染色时正常的细胞也会有一定的染色背景。

本产品的染色原理决定了本产品只能用于培养的细胞或者组织的细胞自噬荧光染色检测,不能用于冻存的或固定的细胞、组织或者组织切片的染色检测。

使用本产品染色后可以通过荧光显微镜拍照观察,也可以通过荧光酶标仪或流式细胞仪进行荧光检测。

荧光显微镜观察时可以使用紫外区激发光激发,发出绿色荧光。

荧光酶标仪或流式细胞仪推荐的激发波长为335nm (330-360nm 均可),发射波长为512nm (510-540nm 均可)。

本产品用于细胞自噬染色的效果参考图1。

Product Data SheetTrigonox BDi-tert-butyl peroxideTrigonox® B is a pure peroxide in liquid form.CAS number110-05-4EINECS/ELINCS No. 203-733-6TSCA statuslisted on inventory Molecular weight 146.2Active oxygen contentperoxide10.94%SpecificationsAppearance Clear liquidAssay≥ 99.0 %ApplicationsTrigonox® B (Di-tert-butyl peroxide) can be used for the market segments: polymer production, polymer crosslinking and acrylics production with their different applications/functions. For more information please check our website and/or contact us.Half-life dataThe reactivity of an organic peroxide is usually given by its half-life (t½) at various temperatures. For Trigonox® B in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:0.1 hr at 164°C (327°F)1 hr at 141°C (286°F)10 hr at 121°C (250°F)Formula 1kd = A·e-Ea/RTFormula 2t½ = (ln2)/kdEa153.46 kJ/moleA 4.20E+15 s-1R8.3142 J/mole·KT(273.15+°C) KThermal stabilityOrganic peroxides are thermally unstable substances which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used for transport is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT80°C (176°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 will occur over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.Ts Max.40°C (104°F) andTs Min.-30°C (-22°F) to prevent crystallizationNote When stored according to these recommended storage conditions, Trigonox® Bwill remain within the Nouryon specifications for a period of at least 6 months afterdelivery.Packaging and transportIn North America Trigonox® B is packed in non-returnable, five gallon polyethylene containers of 30 lb net weight and steel drums of 100 or 340 lb net weight.

Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:XMD8–87 is a potent TNK2 inhibitor with IC 50 values of 38 and 113 nM for the D163E and R806Q mutations, respectively.IC50 & Target: IC50: 38 nM (TNK2, D163E mutation), 113 nM (TNK2, R806Q mutation)[1]In Vitro: XMD8–87 potently inhibits the growth of the TNK2 mutant expressing cell lines while having little or no effect on the control cells out to the highest tested concentrations (1,000 nM). XMD8–87 has IC 50s of 38 nM and 113 nM for the D163E and R806Q mutations. The effects of XMD8–87 on TNK2 cell lines are largely due to on–target effects on TNK2. Auto–phosphorylation of overexpressed TNK2 mutants could be blocked with TNK2 inhibitor XMD8–87[1].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]Kinase targets are tested with biochemical enzymatic kinase assays using the SelectScreen Kinase Profiling Service to determine IC 50 values. The compounds (XMD8–87) are assayed at 10 concentrations (3–fold serial dilutions starting from 1 μM) at an ATP concentration equal to the ATP Km [1].Cell Assay:[1]Cells are treated with the following inhibitors for 72 hours: dasatinib, AIM–100, XMD8–87 and XMD16–5. Cell viability is measured using a methanethiosulfonate (MTS)–based assay and absorbance (490 nm) is read at 1 and 3 hours after adding reagent [1].References:[1]. Maxson JE, et al.

tries. The right to prescribe off-label drug was defined in Britain and Ireland; b) Medical staff had to take the responsibility of off-label drug use in the country where the duty regulations were formulated; and c) Ten countries published guidelines or statements related to off label drug use by their official departments and academic organizations. And the regulation included the following procedures: firstly, to obtain the relative information and evidence; secondly, to get the informed consent; thirdly, to be approved by the ethics committee and/or pharmacy administration committee; fourthly, to record the reasons and effectiveness of off-label use; fifthly, to monitor the adverse reactions of off-label drug use. Besides monitoring the medical institutes, the pharmaceutical companies had also be monitored which included the following 3 aspects: a) to require companies to train specialized staffs to answer the questions related to off-label drug use; b) to open the contact information of medical departments of companies; and c) to prohibit preaching and advertising the off-label drug use. Conclusion Off-label drug use has its rationality and necessity. To protect the safety of patients, avoid the risk for hospitals and medical staffs, it requires formulating relative regulations soon in order to manage the off-label drug use in China. As a developing country, China is different from the developed countries in health care system. Therefore, when formulating the regulations, it is necessary to perform evidence-based evaluation on each country’s laws, regulations and guidelines about off-label drug use, with Chinese national conditions and experts’ opinions in combination. After a regulation is preliminarily drawn up, it needs to be put into pilot practice, and then revised and spread to the whole country.

但对于白血病/淋巴瘤免疫分型,国际上迄今为止也没有统一的抗体组合。

在2000年国际细胞分析学会(ISAC)大会上,临床血细胞计数协会组织了一次国际专家会议,以期对检测血液淋巴系统肿瘤所需最少、最有效的单抗数达成共识。

75%与会者一致认为,对于慢性淋巴系统增殖性疾病(CLD)有9种单抗:CD5,CD19,κ,λ,CD3,CD20,CD23,CD10,CD45对初诊来说是最基本的。

淋巴瘤和CLD相似,需要至少12-16种单抗。

对于急性白血病(AL),75%的与会者认为大约13-15种单抗是最基本的:CD10,CD19,CD79a,CD13,CD33,CD34,CD45,CD2,MPO,CD7,CD14,CD3,HLA-DR等,对初步鉴别白血病系列是必需的。

其他一些(CD16,CD56,CDw65,TdT,cyCD3)可能对某些病例有用。

几乎所有的投票者都认为,要对急性白血病完善分类所需单抗的恰当数量平均为20-24种。

但这些抗体之间组合也是一大难题,目前也无统一规定(如表二)。

大会多数发言者(11/13)指出,对已确诊病人的监护和分期来说,仅需较少单抗。

抗体的质量控制是实验的关键环节。

抗体的质量包括其特异性、灵敏度、精密度。

3-TYP_DataSheet_MedChemExpress

Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:3–TYP is a selective SIRT3 inhibitor, with an IC 50 of 16 nM, more potent over SIRT1 (IC 50=88 nM), SIRT2 (IC 50=92 nM).IC50 & Target: IC50: 16 nM (SIRT3), 88 nM (SIRT1), 92 nM (SIRT2)[3]In Vitro: 3–TYP inhibits melatonin–enhanced SIRT3 activity but does not affect SIRT3 protein expression. 3–TYP pretreatment reverses the protective effects of melatonin on cadmium (Cd)–induced mitochondrial–derived O2•- production and autophagic cell death.3–TYP significantly attenuates melatonin–induced increases in deacetylated–SOD2 expression and SOD2 activity in HepG2 cells exposed to Cd [1].In Vivo: 3–TYP (50 mg/kg, i.p.) does not significantly influence the LVEF, LVFS, infarct size, serum LDH levels, apoptosis, and oxidative stress compared with those of the Sham group. Moreover, 3–TYP has little effect on gp91phox, Nrf2, NQO 1, Bax, Bcl–2, Caspase–3,and cleaved Caspase–3 expression levels, compared with the Sham group. 3–TYP significantly decreases SIRT3 activity and increases the acetylation of SOD2 compared with that in the control group, without influencing SIRT3 expression. 3–TYP attenuates thecardioprotective effects of melatonin by decreasing the LVEF and LVFS after 24 hour of reperfusion. 3–TYP also increases the infarct size, serum LDH levels, and apoptotic ratio compared with those in the IR+Mel group [2].PROTOCOL (Extracted from published papers and Only for reference)Cell Assay:[1]Cell viability is analyzed using Cell Counting Kit–8. Briefly, 1×104 cells are inoculated into 96–well plates. After being treated, 90 μL of medium and 10 μL of CCK–8 solution are added to each well. The cells are then incubated at 37°C for 2 h. After incubation, the absorption at 450 nm is measured using an Infinite? M200 Microplate Reader. The results are expressed as apercentage of the control. The cell death is also evaluated using the trypan blue assay. HepG2 cells are plated in the 6–well plates (5×105 cells per well) and incubated for 24 h. After being treated with Cd or melatonin, the cells are detached with 300 μLtrypsin–EDTA solution. The mixture of detached cells is centrifugated at 300 g for 5 min. Then, the residue is combined with 800 μL trypan blue solution and dispersed. After 3 min staining, cells are counted using an automated cell counter. The dead cells are stained with the blue color. Cell mortality (%) is expressed as percentage of the dead cell number/the total cell number.Animal Administration: 3–TYP is formulated in 1% ethanol.[2]In brief, male C57BL/6 mice are anesthetized with 2% isoflurane, andmyocardial ischemia is produced by temporarily exteriorizing the heart via a left thoracic incision and placing a 6–0 silk suture slipknot around the left anterior descending coronary artery. After 30 minutes of myocardial ischemia, the slipknot is released, and the myocardium is reperfused for 3 hour (for western blot analysis and oxidative stress measurement) or 24 hour (for cardiac function,apoptotic index and infarct size determination). Sham–operated mice undergo the same surgical procedures except the suture placed under the left coronary artery is not tied. Ten minutes before reperfusion, mice are randomized to receive either vehicle (1% ethanol)or melatonin (20 mg/kg) by intraperitoneal injection. C57BL/6 mice are randomly divided into the following groups: (i) Sham group:mice underwent the sham operation and are treated with vehicle (1% ethanol); (ii) Mel group: mice are treated with melatonin (20Product Name:3–TYP Cat.

Expressing the protein without the GS domain, which has been shown to regulate the kinase activity, creates a constitutively active kinase that is able to phosphorylate GST-Smad3. Test the effects of SB-431542 on ALK5 and ALK4 kinase activity with GST-Smad3 as substrate.Reaction Conditions The Kinase assays were performed with 65 nM GSTALK5 and 184 nM GST-Smad3 in 50 mM HEPES, 5 mM MgCl2, 1 mM CaCl2, 1 mM dithiothreitol, and 3 μM ATP. Reactions were incubated with 0.5 μCi of [33P]γATP for 3 h at 30°C.Applications SB-431542 is a selective ALK5 inhibitor with little activity against p38 MAPK. SB-431542 also inhibits ALK4 activity. Which is consistent with the degree of homology between these kinases, such that ALK4 is the closest related kinase to ALK5. This data clearly demonstrated that SB-431542 is a potent and selective inhibitor of ALK5 and ALK4, with slightly higher selectivity for ALK5.Cell experiment [1]:Cell lines Renal proximal tubule epithelial cells (RPTEC)Product Data SheetPreparation Method Cells were grown in Earle’s minimum essential medium supplemented with 10% fetal calfserum, penicillin (5 units/ml), and streptomycin (5 ng/ml). Cells were serum-starved for 24 hbefore treatment.Reaction Conditions Cells were treated with TGF-β1 (5 ng/ml) plus increasing concentrations of SB-431542 (50,250, 500, and 700 nM).Applications SB-431542 could be used to evaluate whether ALK5 activity is required for TGF-β1-inducedtranslocation of Smad3. SB-431542 at a concentration of 1 μM significantly reduced the TGF-β1-induced nuclear accumulation of Smad proteins. Thus, SB-431542 selectively inhibitsTGF-β1–induced Smad translocation without affecting BMP-induced Smads.Animal experiment [2]:Animal models Male Sprague-Dawley rats aged 5 weeks, weighing 200-220 gPreparation Method Rats lived in air served as control groups, and rats lived in an air condition incubatorcontaining 10% O2 to simulate chronic hypoxia animal model, and served as model groups.Model groups were treated with daily intraperitoneal injections of the SB-431542 for 28days.Dosage form 10 mg/kg; 20 mg/kgApplications SB-431542 inhibited the proliferative activity as a function of exposure time andconcentration. Treated rats with SB-431542 caused more pathological changes in vascularadventitia, and the severity of the changes varied from slight to moderate depending on concentrations. In addition, the pulmonary arteries in the hypoxia-induced model groups hadgreater amounts of collagen fibers than that of the control groups. In comparison, collagenfibers were significantly reduced after treatment with SB-431542 (P < 0.01).References:[1]. Laping NJ, et al.

SB-431542, a specific inhibitor of the TGF-β type I receptor inhibits hypoxia-induced proliferation of pulmonary artery adventitial fibroblasts. Pharmazie. 2016 Feb;71(2):94-100.BackgroundSB-431542, a small molecule inhibitor of the type I TGF-β receptor, blocks intracellular mediators of TGF-1 signaling,which leads to decreased TGF-β1–mediated proliferation, cytokines and collagen expression. In clinical settings,SB-431542 is widely used to treat respiratory asthma, and inhibits proliferation and synthesis of adventitial fibro in the process of pulmonary vascular remodeling.[1]In vitro study indicated that SB-431542 is able to inhibit ALK5 with an IC50 of 94 nM and other type I receptors, such as ALK4. Although SB-431542 inhibited ALK4 with an IC50 of 140 nM. Moreover, SB-431542 inhibited TGF-β1–induced collagen Iα1 and PAI-1 mRNA with IC50 values of 60 and 50 nM, respectively. In addition, SB-431542 inhibited TGF-β1–induced fibronectin mRNA and protein with IC50 values of 62 and 22 nM, respectively. These data demonstrate for the first time that ALK5 activity is required for TGF-β1 regulation of extracellular matrix markers FN, collagen Iα1,and PAI-1 mRNA.[1]In vivo study demonstrated that SB-431542 has the capacity to inhibit TGF-β1-induced gene expression. SB-431542is recognized as a important inhibitor of the TGF-β1 receptors in blocking TGF-β1/Smads signal pathways in vascular remodeling. Moreover, hypoxia-induced vascular remodeling can significantly increase the amount of cytokines and collagen in vascular adventitia. However, after the treatment of SB-431542, attenuation of the fibrosis promoting effects of TGF-β1, including TGF-β1-induced cell proliferation, cell motility, cell migration and cell synthesis were observed. Therefore, it is significant to the identify the potential of SB-431542 for the treatment of hypoxia-induced pulmonary hypertension.[2]References:[1]. Laping NJ, et al.

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. AST -oxoglutarate + L-aspartate L-glutamate + oxaloacetate MDH oxaloacetate + NADH + H + L-malate + NAD +SPECIMEN COLLECTION AND PREPARATION (5) Serum:- Use serum free from haemolysis.Plasma:- EDTA or heparin can be used as the anticoagulant.Plasma should be separated from cells within one hour after collection.Specimens should be refrigerated if not used immediately:-Specimens stored longer than 3 days should be frozen at -20︒C.REAGENT COMPOSITIONContents Concentrations in the TestR1a.

态。膜脂类分子在相变温度以上条件下主要有侧向扩散、旋转、左右摇摆、伸缩振荡、翻转 及异化运动等方式。膜蛋白的运动方式大体分为侧向及旋转运动,主要受脂质双分子层的影 响。脂肪酸不饱和键含量和链的长度明显影响着膜脂流动性,不饱和键的存在会降低膜脂分 子间排列的有序性,从而增加膜的流动性,短链能减低脂肪酸链尾部相互作用,在相变温度 下,不易于凝集,此外,脂肪酸烃链围绕 C- C 键由全反式构型到歪扭(CAUCHE)的旋转异 构运动,也可使流动性加大。
按下列公式计算荧光偏振度 P: P=(IVV-GIVHIHV)/(IVV+GIVH) 其中校正因子 G=IHV/IHH
-3-
式中 IVV:起偏和检偏器光轴同为垂直方向时测得的荧光强度; IVH:起偏和检偏器光轴分别为垂直和水平方向时测得的荧光强度。 IHV:起偏和检偏器光轴分别为水平和垂直方向时测得的荧光强度; IHH:起偏和检偏器光轴同为水平方向时测得的荧光强度。 P 值越大 ,流动性越小;P 值越小,流动性越大。
体洒落。 ● 染色液为 DMSO 溶液,冬季气温较低时在室温时为凝固状态,极易粘附在管壁、吸头壁。注意需要
加热溶解,吸头也需要放在培养箱预热,否者容易再次凝固在吸头内壁产生损耗。 ● 细胞处理需要小心操作,尽量避免人为的损伤细胞。 ● 染色后立即进行分析。 ● 标记的条件因细胞种类而异,根据不同样本的实际染色结果做相应调整,在每次实验前,请先确
定最佳条件。 ● 以下步骤仅供参考。请根据实际实验方案设计或者参考文献实验。
1、 染色工作液的配制: 用稀释液稀释 TMA-DPH 探针 1000 倍-10000 倍,配制成 TMA-DPH 染色工作液。

细胞粘附的检测方法
养时间。
包被: 1、 96 孔板每孔加入 100ul 包被液。 2、 将培养板置 2-8°C 过夜。 3、 移除包被液,用洗涤液洗涤 2-3 次。
细胞接种: 1、 待测定细胞处理好后,用胰酶消化,PBS 洗涤,然后用相应培养基重悬,制成细胞
悬液。 2、 按 5×104 细胞/孔接种 96 孔板,建议设 3-5 个复孔。同时设立对照组,即孵育后不
体损失导致试剂量不够用。 ● 细胞处理需要小心操作,尽量避免人为的损伤细胞。离心力在不损失细胞的前提下尽可能小,重悬
细胞是动作要轻柔,避免多次反复的激烈吹打。不用涡旋振荡器。 ● 染色培养时间根据细胞种类的不同和每孔内细胞数量的多少而异。一般情况下,白细胞较难染色,
因此需要较长的培养时间。培养时间一般为 1- 4 小时,但在培养 30 分钟左右即可取出肉眼观察 染色程度 (根据细胞种类而定,需要摸索一下条件)。当使用标准 96 孔板时,贴壁细胞的最小接 种量至少为 1,000 个/孔 (100 μl 培养基)。检测白细胞时的灵敏度相对较低,因此推荐接种量不 低于 2,500 个/孔 (100 μl 培养基)。如果要使用 24 孔板或 6 孔板实验,请先计算每孔相应的接 种量,并按照每孔培养基总体积的 10%加入染色液 B。 ● 有条件的情况下建议采用多通道移液器,可以减少平行孔间的差异。加染色液 B 试剂时,建议斜
