Figure 1. Ascorbate induces cytotoxicity in cancer cells, but not in primary hepatocytes.

Figure 1

Cell viability was measured using either the CellTiter-Glo® Luminescent cell viability assay (Promega) (A and C) or the MTT assay (B) after two hour treatment with various concentrations of ascorbate (1, 3, 5, 10, or 20 mM) (A and B) and the addition of catalase (100 μg/mL) to the media (C). Error bars represent the SEM (n=3). Some error bars may be smaller than the symbol.
