WST-1 [CAS 150849-52-8]

WST-1 is a kind of water-soluble tetrazolium salt. WST induces the intracellular mitochondrial dehydrogenase to conduct NADH-dependent enzyme digestion reaction, releasing the water-soluble methyl benzene product. WST-1 can be used for the detection of cell proliferation and cytotoxicity, via the determination of the light absorption value at 450 nm[1].
