wst-1

WST-1 是一种具有细胞毒性的水溶性四唑盐，诱导细胞内线粒体脱氢酶进行 NADH 依赖性酶解反应，释放出水溶性甲基苯产物。WST-1 可通过检测吸收值来检测细胞增殖和细胞活性，可用于WST-1平板测定法测定超氧化物歧化酶活性。

XTT is a cell-impermeable, negatively charged tetrazolium dye that produces a water-soluble formazan when reduced at the cell surface by cellular-derived NADH and an electron mediator.1,2It is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis.3 1.Berridge, M.V., Tan, A.S., and Herst, P.M.Tetrazolium dyes as tools in cell biology: New insights into their cellular reductionBiotechnol.
