The effect of CoCl2 on viability. (A) Cell viability of MCF7, T-47D, BT-474 and ZR-75-1 cells in % after 48 h exposure to 0.1–1000 µM CoCl2. The bars and whiskers represent mean values with 95% confidence intervals (95% CI). The fluorescence value (i.e. viability) in each biological replicate (n = 6) was tested against the mean of the controls (n = 6). The mean of the controls was set to 100%. (B) Comparison of viability at 100 µM CoCl2 in MCF7 (p = 0.82), T-47D (p = 0.015), BT-474 (p = 0.0022) and in ZR-75-1 (p = 0.0022). The bars represent median values and the whiskers represent 95% CI. * = p < 0.05, ** = p < 0.01, ns = non-significant
