In Vitro	WST-1 is used for a wide range of assays that include cell viability, proliferation, plasma membrane electron transport system, superoxide generation, superoxide dismutase, and xanthine oxidase assay[1]. A water-soluble formazan dye is produced from the reduction of WST-1 tetrazolium, of which optical density at 450 nm is measured to evaluate cell viability[1].
