Cell Counting Kit-8 (CCK-8) is designed to detect cell proliferation and cell toxicity based on WST-8 is reduced by dehydrogenases in cells to give an orange colored product (formazan). The amount of the formazan in cells is directly proportional to the number of living cells.
Features & Benefits
One-bottle, ready-to-use solution. • The product (formazan) produced by WST-8 is water soluble, No organic solvents or isotopes required. And the formazan is stable and safe. • The detection sensitivity using CCK-8 is higher than assays using other tetrazolium salts such as MTT, XTT, MTS or WST-1. • The same cells can be used for other cell assays because of the low toxicity of CCK-8.
CCK-8 is stable over one year at 0-5°C with protection from light. Store it at -20°C for longer storage. Repeated thawing and freezing causes an increase in the background, which interferes with the assay. Please store the kit at 0-5°C for frequent use.
