Fig. 3. FACS analysis of H2O2accumulation in NB4 and selenite-pretreated NB4 cells. NB4 cells were pretreated without (NB4) or with 100 nmol/L sodium selenite for 9 days (NB4-sele) and then treated with the indicated concentrations of As2O3 for 24 hours. DCFH-DA was added 1 hour before the addition of As2O3, and the oxidized DCF was analyzed by FACS.
