FACS analysis of DNA fragmentation following exposure to GPS. Cells exposed to 1, 3 or 5 puffs GPS were harvested 24 hours post-exposure and analysed for DNA fragmentation using BrdU labelling and PI counterstaining. A) untreated cells, B) 2 μM STS, C) 1 puff, D) 3 puffs, E) 5 puffs. F) Bar chart showing the cumulative results for PI-only stained cells and PI/BrdU stained cells, derived from 3 different sets of experiments (mean values ± SD). * P < 0.0001 compared with control, ** P < 0.001 compared with control (one-way ANOVA).
