Ready-to-use solution, containing WST-1 and an electron coupling reagent.Cellular proliferation requires the replication of genomic DNA. Thus, monitoring DNA synthesis is an indirect parameter of cell proliferation, as well as being suitable for the study of the regulation of DNA synthesis. [3H]-thymidine has traditionally been used to label the DNA of replicating (cycling) cells. To circumvent the disadvantages associated with the use of the [3H]-thymidine, nonradioactive alternatives based on 5-bromo-2′-deoxyuridine (BrdU) have been developed. The use of chemiluminescence technology provides enhanced sensitivity and a broad measurement range.Colorimetric assay (WST-1 based) for the nonradioactive quantification of cell proliferation, cell viability, and cytotoxicity.Other Notes仅用于生命科学研究。不可用于诊断。PrincipleThe stable tetrazolium salt WST-1 is cleaved to a soluble formazan by a complex cellular mechanism that occurs primarily at the cell surface. This bioreduction is largely dependent on the glycolytic production of NAD(P)H in viable cells. Therefore, the amount of formazan dye formed directly correlates to the number of metabolically active cells in the culture.
Cells grown in a 96-well tissue culture plate are incubated with the WST-1 reagent for 0.5 - 4 hours. After this incubation period, the formazan dye formed is quantitated with a scanning multi-well spectrophotometer (ELISA reader). The measured absorbance directly correlates to the number of viable cells.
Cell proliferation and viability assays are of particular importance for routine applications in cell biology. Tetrazolium salts (e.g., MTT, XTT, WST-1) are particularly useful for this type of analysis. Tetrazolium salts are cleaved to formazan by the succinate-tetrazolium reductase system (EC 1.3.99.1) which belongs to the respiratory chain of the mitochondria, and is only active in metabolically intact cells.Preparation NoteWorking concentration: For best results, add 10 μl/well Cell Proliferation Reagent WST-1 to the cells already cultured in 100 μl/well (1:10 final dilution).
Using the 100 μl/well cell culture volume, one vial will be sufficient to perform 2500 tests (25 microplates).
Note: If the cells are cultured in 200 μl/well, add 20 μl/well Cell Proliferation Reagent WST-1.
Storage conditions (working solution): 2 to 8 °C
Note: When precipitates or turbidity are observed upon thawing, warm up the solution to 37 °C for 2 to 10 minutes and agitate to dissolve the precipitates.Centrifugation is not recommended because the working concentration would decrease. After being dissolved, the WST-1 reagent can be used without any limitations. Please store as follows:
Once thawed, store at 2 to 8 °C, protected from light, for up to four weeks. However please note that the solution may become viscous. If so, warm up the solution to 37 °C for 2 to 10 minutes as described above.
Long storage
For long storage, aliquots of WST-1 can be stored in plastic tubes at -15 to -25 °C until the expiry date.ApplicationThe Cell Proliferation Reagent WST-1 is used for the nonradioactive, spectrophotometric quantification of cell proliferation and viability in cell populations using the 96-well-plate format.

文献和实验MTT的替代产品—XTT,WST-1,CCK-8(WST-8)
与电子偶合剂(例如 PMS )联合应用时,其所产生的水溶性的甲臜产物的吸光度与活细胞的数量成正比。 优点: 1 、使用方便,省去了洗涤细胞; 2 、检测快速; 3 、灵敏度高,甚至可以测定较低细胞密度; 4 、重复性优于 MTT 。 缺点: XTT 水溶液不稳定,需要低温保存或现配现用。 3. WST-1 WST-1是一种类似于MTT的化合物,在电子耦合
kandr20051 最近在做细胞实验,用的是WST-1检测细胞活性。在检测的前72个小时,实验都符合预期,给药组的OD值比阴性对照组的要低,但是到了96个小时以后,WST-1的结果就逆转了。给药组的OD值远远高于阴性对照组。 但最奇怪的是,WST-1的检测结果与我镜下观察到的细胞形态和多少完全不同! 这是阴性对照组 这是给药组的 为什么会出现这种结果呢?
WST-8 Analysis of Cell Viability During Osteogenesis of Human Mesenchymal Stem Cells
WST-8 is one of the newer generation formazan-based dyes, which release the converted product into the medium in a soluble form. This allows for a non-destructive determination of viability enabling the cells to be subject
