ATP-based cell viability assay is superior to trypan blue exclusion and XTT assay in measuring cytotoxicity of anticancer drugs Taxol and Imatinib, and proteasome inhibitor MG-132 on human hepatoma cell line HepG2

Abstract

Acute cytotoxic effects of tested compounds could be revealed. However, results were significantly different from each other with ATP assay being the most sensitive one under the conditions tested. Thus, acute cytotoxicity can be dramatically underestimated if only standard XTT test is used.
