China CCK-8 Cell Counting Kit Suppliers | Factory Direct Cell Proliferation and Cytotoxicity Detection

The Cell Counting Kit-8, commonly known as CCK8 or WST-8, is a highly effective tool for the rapid and sensitive detection of cell proliferation and cytotoxicity. This kit utilizes WST-8, a chemical compound scientifically referred to as 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfonobenzene)-2H-tetrazole monosodium salt, making it an essential component in cell biology research.

How the WST-8 method works: The CCK8 kit operates by leveraging the capabilities of electron-coupled reagents that facilitate the reduction of WST-8 by mitochondrial dehydrogenase. This reaction leads to the formation of a highly water-soluble orange formazan dye. The intensity of the color produced is directly proportional to the cell proliferation rate and inversely proportional to cell cytotoxicity. By measuring the optical density (OD) at a wavelength of 450nm using an enzymoscope, researchers can indirectly quantify the number of viable cells present in their samples.
