Cell counting kit 8 cck 8

Manufactured by ZOMANBIO
Sourced in China

The Cell Counting Kit-8 (CCK-8) is a colorimetric assay that can be used to determine the number of viable cells in cell proliferation and cytotoxicity assays. The kit utilizes a water-soluble tetrazolium salt to measure the activity of cellular dehydrogenases, which directly correlates to the number of living cells in the culture.

Evaluating Compound Cytotoxicity on Vero Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cytotoxic effect of compounds on Vero cells was assessed using the Cell Counting Kit-8 (CCK-8, ZOMANBIO, Beijing, China) according to manufacturer's instructions. Briefly, cells were seeded onto a 96-well cell plate and cultured until they grew into a single layer. The culture medium was removed and washed with PBS twice. The medium was replaced with cell maintenance solution in the presence of serial dilutions of each compound. The plates were incubated for 24 ​h when the medium was replaced with fresh DMEM containing 10% CCK-8 solution and cultured for 1.5 ​h. Then the OD value for each well was detected at 450 ​nm on a microplate reader (BMG Labtech POLAR star Omega). The assay was repeated three times. Cytotoxicity was analyzed according to the following formula: Cytotoxicity (%) ​= ​[(Abs sample) – (Abs blank)]/[(Abs negative control) – (Abs blank)] ​× ​100.

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.
