Effect of in vitro As exposure on DNA damage and repair function in a cultured Jurkat lymphoblast cell line. Cultured cells were exposed in vitro to 0 or 1 μM As for 24 hr (n = 6 independent cultures). Cells from each culture were analyzed by single-cell gel electrophoresis immediately after harvest (time = 0 hr), after a 2-hr in vitro challenge with 4 μM 2-AAAF (time = 2 hr), and after a 4-hr repair period (time = 6 hr). See “Materials and Methods” for details. Values represent mean ± 95% confidence interval.

*Statistically significant compared to the control group (p < 0.05).
