The Colorimetric Cell Viability Kits I allows for easy and reliable colorimetric determination of viable cell numbers with excellent sensitivity and linearity. The kit utilizes the tetrazolium salt WST-8 that is reduced to water-soluble, orange formazan dyes by dehydrogenases present in viable cells. The absorbance of the formazan dye is proportional to the number of metabolically active cells and can be measured directly from a 96-well plate without additional processing.
