Cell Counting Kit-8 (CCK-8) is a ready to use solution for cell viability assays and cell proliferation assays. The kit uses WST-8 tetrazolium salt which is reduced by dehydrogenases in living cells to give a brightly coloured dye. The dye generated is directly proportional to the number of live cells enabling colorimetric quantitation of viable cell number.Â
Key features:
Ready to use solution
Results after 1-4 hour incubation
The Cell Counting Kit-8 assay is more sensitive than other tetrazolium salt-based assays such as XTT, MTS and MTT.
Low cytotoxicity and high stability make this kit suitable for long incubation time (24-48 hours)
Description
Ready to use solution for colorimetric quantitation of viable cell number.
Cytotoxicity test of Staurosporine on HEK293T cells
HEK293T cells were plated at 10,000 cells per well in 100 µL in a 96 well plate and incubated overnight. Cells were treated with different concentrations of Staurosporine (HB0590) for 4 hours before adding 10 µL of CCK-8. Absorbance at 450 nm was measured after 3 hours at 37°C and cell viability was calculated as a percentage of untreated cells.
Cell Counting Assay
HEK 293T cells at 0 to 300,000 cells in 100 µL were plated in a 96 well plate. 10 µL of CCK-8 were added to each well and the plate was incubated at 37°C for 1 hour and absorbance was measured at 450 nm using a plate reader.
Cytotoxicity test of SDS on HEK293T cells
HEK293T cells were plated at 10,000 cells per well in 100 µL in a 96 well plate and cultured overnight. Cells were treated with different concentrations of SDS for 2 hours before adding 10 µL of CCK-8. Absorbance at 450 nm was measured after 3 hours at 37°C and cell viability was calculated as a percentage of untreated cells.
