Effects of As2O3 (arsenic) on the apoptotic rate of K562 and the various HL-60 cell types.
Cells were treated with the indicated concentrations and exposure intervals of As2O3, and percentage apoptotic cells were characterized as those that stained with annexin-V and excluded PI, using the annexin-V assay kit (see “Materials and Methods”). Data represent the mean of 3 independent experiments.
