G-Biosciences' CytoScan™ WST-1 Cell Proliferation Assay is a sensitive and accurate assay for cell proliferation and cytotoxicity

G-Biosciences' CytoScan™ WST-1 Cell Proliferation Assay principle is based upon the reduction of the high sensitivity tetrazolium salt, WST-1, to formazan by cellular dehydrogenases. The generation of the dark yellow colored formazan is measured at 420 to 480nm (optimal at 440nm) and is directly correlated to cell number.

G-Biosciences' CytoScan™ WST-1 Cell Proliferation Assay is supplied in a kit that contains components sufficient for performing up to 500 assays.

The assay is highly convenient as it is performed in a single cell tissue culture well and requires no washing, harvesting or solubilization of cells. Adherent or suspension cells are cultured in a microplate and then incubated with WST-1 and the assay is monitored with a spectrophotometer.
