Figure 2. Genotoxic effects in HepG2 cells assessed with the comet assay. Data are reported as the mean OTM (Olive Tail Moment) and 95% confidence intervals of 600 scored nucleoids per Arianor Ebony dye concentrations. NC: negative control; PC: positive control. The induction factors (IF) shown in the graph are the quotient of the median values of OTM of exposed cells and PC cells and the median values of OTM of the NC cells. *P<0.05 compared to NC according to Tukey's test.
