CCK 8 Kit

The Cell Counting Kit 8, also known as ccK-8, is an effective and safe colorimetric detection method extensively utilized in Cell proliferation or toxicity experiments to accurately quantify the population of viable cells. This non-radioactive technique is highly sensitive, allowing researchers to determine the precise number of living cells with utmost reliability.

Cck-8 is an improved version of MTT, designed to simplify the process of detecting cell activity through a quick and minimally toxic solution. The solution, which is composed of WST-8, a water-soluble tetrazole salt, can be directly applied to cell samples without any prior preparation. When combined with an electron-coupled reagent, WST-8 can be reduced by a mitochondrial enzyme called dehydrogenase, resulting in the production of a distinct orange dye. The intensity of this dye directly correlates with the number of living cells in the sample, allowing for an accurate measurement of cell proliferation or drug toxicity through colorimetry. This kit is highly versatile and can detect changes in cell cycle, apoptosis, and more, making it a valuable tool for researchers. While it may require the digestion of tissue samples into a single cell state prior to use, Cck-8 remains a top choice for efficient and effective cell detection.
