Colorimetric Cell Viability Kit II (WST-1)
Colorimetric cell viability and cytotoxicity detection
The Colorimetric Cell Viability Kits II allows for easy and reliable colorimetric determination of viable cell numbers with excellent sensitivity and linearity. The kit utilizes the tetrazolium salt WST-1 (Kit II) 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.
