Ascorbic acid protects B4G12 and ARPE-19 cells from oxidative stress. B4G12 and ARPE-19 were pretreated with ascorbic acid (AA) for two days and further treated with paraquat (2 mM for ARPE-19, 0.2 mM for B4G12) for five days. (A) The time-dependent protective effect of ascorbic acid (1 mM) on B4G12 and ARPE-19 cells was examined on days 0–5. (B) The dose-dependent protective effect of ascorbic acid (0 to 2 mM) on B4G12 and ARPE-19 cells was examined on day five. Cell morphology was observed using phase-contrast microscopy, and images were captured at the same spot on different days. The scale bar represents 100 µm.
