WST-1 Proliferation Assay Kit provides an easy to use tool for studying the induction and inhibition of cell proliferation in any in vitro model. The assay is based on the reduction of tetrazolium salt WST-1 to soluble formazan by electron transport across the plasma membrane of dividing cells. This kit will also allow investigators to screen drug candidates involved in regulation of cell cycle.

• Colorimetric, non-radioactive assay for assessing cell viability and proliferation
• Tetrazolium salt, WST-1, is reduced to a soluble purple formazan by trans-plasma membrane electron transport from NADH via an electron mediator
• Detect 1000 to 200000 cells per well
• Rapid assay, get results in <4 hours
