Dojindo’s highly water-soluble tetrazolium salt, WST-8, is reduced by dehydrogenase activities in cells to give a yellow-color formazan dye, which is soluble in the tissue culture media. The amount of the formazan dye, generated by the activities of dehydrogenases in cells, is directly proportional to the number of living cells. The detection sensitivity of CCK-8 is higher than the other tetrazolium salts such as MTT, XTT, MTS or WST-1.
Key features:
- Sensitivity - highly sensitive dye for cell-based assay.
- Cytotoxicity of reagents - continuous culture is possible without killing cells
- Stability - Cell Counting Kit-8 is a ready-to-use solution. It is also stable at 4ºC for 1 year. Your assay can be done anytime without thaw and freeze.
