Effects of resveratrol on the cell viability of ARPE-19 cells.

Notes: The cell viability was determined by the WST-1 assay. Confluent monolayer cells were incubated with indicated concentrations of resveratrol (0, 25, 50, 100, 200, 400, and 800 µM, respectively) for 24 h. The results are the mean values ± SEM of three independent experiments. ***P<0.001 versus the control group.

Abbreviations: NS, not significant; SEM, standard error of the mean; WST, 4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate.
