Cell Counting试剂盒8 (WST-8 / CCK8)

产品详情

Cell Counting Kit 8 / CCK-8 Assay Kit / WST-8 Assay Kit ab228554 provides a convenient and robust way of performing a cell viability assay.

How the CCK-8 assay works

The CCK-8 assay uses a water-soluble tetrazolium salt to quantify the number of live cells by producing an orange formazan dye upon bio-reduction in the presence of an electron carrier. WST-8 solution is added directly to the test cells, no pre-mixing of components is required. WST-8 tetrazolium salt is reduced by cellular dehydrogenases to an orange formazan product that is soluble in tissue culture medium.

The amount of formazan produced is directly proportional to the number of living cells by monitoring absorbance increase at 460 nm. The excellent stability and little cytotoxicity of WST-8 solution make the kit useful for the assays that require long incubation (such as 24 to 48 hours).

CCK8 assay protocol summary

• - Prepare cells in a 96-well plate (100 µL/well).
• - Add 10 µL of WST-8 Solution to each well.
• - Incubate at 37°C for 1 - 4 hours.
• - Monitor absorbance at OD = 460 nm.
