生物活性

WST-1 is a Tetrazolium dye, widely used in the cell viability assays. WST-1 produces a water-soluble formazan product (WST-1 formazan) that occurs at the cell surface in NADPH dependent manner in viable cells[1][2].

体外研究
(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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
