Cell counting kit 8 cck 8

Manufactured by Hanheng Biotechnology
Sourced in China

The Cell Counting Kit-8 (CCK-8) is a colorimetric assay used to determine the number of viable cells in a sample. It utilizes a water-soluble tetrazolium salt that is reduced by cellular dehydrogenases, producing a colored formazan dye which can be measured spectrophotometrically. The amount of the formazan dye generated is directly proportional to the number of living cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
