Following 4 h incubation at 37°C with 20 μM of PMS-electron coupling reagent (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy phenyl)-2-(4-sulfophenyl)-2H-tetrazolium inner salt (MTS)/ phenazine methosulfate, the optical density (OD) of the MTS bioreduction product formazan was measured at 490 nm wavelength. OD mean values were normalized to mock treated cells (100% survival). Mean values + SEM (n = 3) *(p<0.05) significant differences vs control (Oneway ANOVA and posthoc Bonferroni).
