Viability of INS-1 832/13 cells after 24-h exposures to iAsIII, MAsIII and DMAsIII: CellTox™ Green. INS-1 832/13 cells were exposed for up to 24 h to iAsIII (a), MAsIII (b), or DMAsIII (c). Cell viability was measured using CellTox™ Green at 0.5, 1, 1.5, and 24 h. Values were normalized to the control at each time point. Mean + SD is shown for four technical replicates. *p < 0.05, +p < 0.01 for comparisons of treated versus untreated (control) cells
