Figure 4. Sensitivity of ARPE-19 cells to hydroquinone oxidative stress in the presence of various concentrations of A2E. The viability of ARPE-19 cells treated with 50–500 µM hydroquinone (HQ) in the presence of 0, 20 nM, 1 µM, or 10 µM A2E for 16 h, followed by 24 h recovery, was measured with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell viability assay. n = 3 for each condition.
