Differences in cytotoxicity evaluation arise first from differences in the biological process being measured. The Neutral Red assay primarily reflects cellular uptake of the dye and lysosomal retention capacity, whereas the MTT assay and the CCK-8 assay mainly reflect dehydrogenase-related ...
CCK-8 (Cell Counting Kit-8) is a colorimetric cell-viability assay system based on the water-soluble tetrazolium salt WST-8. It is widely used for cell proliferation, cytotoxicity, and drug-sensitivity evaluation.
