Product Description
WST-8 is a water-soluble tetrazolium salt used for assessing cell metabolic activity. At neutral pH and in the presence of the intermediate electron acceptor, 1-methoxy phenazine methosulfate, NADPH-dependent cellular oxidoreductases, acting via plasma membrane electron transport, reduce the cell-impermeant WST-8 outside the cell to a water-soluble formazan dye with absorbance max at 460 nm.1,2 It is typically used as a cell viability indicator in cell proliferation assays.
WARNING This product is not for human or veterinary use.
