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

cytotoxicity.  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. The assay principle is based upon the reduction of the tetrazolium salt

WST-1 to formazan by cellular dehydrogenases (see figure below).  The generation of the dark yellow

colored formazan is measured at 420-480nm (optimal at 440nm) and is directly correlated to cell number.




• Uses WST-1, a high sensitivity tetrazolium salt.

• Colorimetric assay.

• Adherent or suspension cells.

• No washing, harvesting or solubilization required.




• For the detection of cell toxicity, death, viability or proliferation.

• Ideal for high throughout screening
