Cytotoxicity and ATP depletion after treatment with CaEP or ECT with bleomycin. (a–d) Relative survival of different normal and tumour cell lines 72 hours after treatment with increasing concentrations of calcium or bleomycin and in combination with electroporation (AM ± s.e.m.; n = 16 wells in 3 independent experiments). (e–h) The relative concentration of intracellular ATP content 1 hour after treatment with increasing concentrations of calcium or bleomycin and in combination with electroporation (AM ± s.e.m.; n = 4 wells in 3 independent experiments). *p < 0.05, statistical comparisons were performed by one-way ANOVA analysis and compared to control groups by Holm-Sidak testing. All data are normalized to the untreated or electroporated-only cells.
