WST-1 是一种水溶性四唑盐。WST-1 诱导细胞内线粒体脱氢酶进行 NADH 依赖的酶切反应，释放出水溶性的甲臜产物。WST-1 可用于细胞增殖与细胞毒性检测，通过测定 450 nm 处的吸光值来反映细胞活力。

Suc-Leu-Tyr-AMC is a fluorescent substrate for calpain I and II, papain (another cysteine protease), and is used to measure the chymotrypsin-like peptidase activity of the 20S proteasome (excitation max: 360 nm; emission max: 460 nm). Suc-Leu-Tyr-AMC can also be cleaved by the Ti protease from E. coli.
