What is wst-1 assay?

The WST-1 Cell Proliferation Assay from Roche is a colorimetric assay that is based on the cleavage of a tetrazolium salt, MTS, by mitochondrial dehydrogenases to form formazan in viable cells. The Cell Proliferation Reagent WST-1 is designed to be used for the non- radioactive, spectrophotometric quantification of cell proliferation, growth, viability , and. Colorimetric assay (WST-1 based) for the nonradioactive quantification of cell proliferation, cell viability, and cytotoxicity. Roche's WST-1 cell proliferation reagent is a simple, colorimetric assay designed to measure the relative proliferation rates of cells in culture. WST-1 produces a highly water soluble formazan upon metabolically active cells, allowing a direct and user-friendly colorimetric measurement of cell viability and.
