Cell counting kit 8

Manufactured by Sangon

The Cell Counting Kit (CCK)-8 is a colorimetric assay used to measure cell viability and proliferation. It utilizes a water-soluble tetrazolium salt that is reduced by cellular dehydrogenases to produce a formazan dye, which can be measured spectrophotometrically. The amount of formazan dye generated is directly proportional to the number of living cells in the culture.

A Cell Counting Kit (CCK)-8 (Sangon Biotech Co., Ltd.) was utilized to evaluate cell viability. In brief, 16HBE cells (100 µl) were seeded in 96-well plates overnight. After treatment or/and transfection, CCK-8 (10 µl) reagent was added to per well and then incubated for another 3 h. Lastly, optical density (OD) value was examined under a microplate reader (Bio-Rad Laboratories, Inc.) at 450 nm.

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.
