Comparison of the cytotoxicity increment in MCTS cultures assessed by MTT and LDH release assays.

Relative to the untreated control, which was normalized to 0% in both assays, reduction in cell viability of treated samples assessed by MTT assay was compared to the elevation in cytotoxicity determined from the LDH release assay. The results were presented as means ± S.E.M. of three independent experiments.
