Fig 2. The effects of combining As3+ and As4S4 on the apoptosis of NB4 and primary APL cells.

Fig 2

(A) The apoptosis of NB4 cells. (B) The apoptosis of primary APL cells. (C) The percentage of apoptotic cells in NB4 and primary APL cells. After 48 h of treatment, the cells were stained with Annexin V-FITC and PI. Q1 and Q3, represent the dead cells and living cells, respectively. Q2 and Q4 were used to calculate the proportion of apoptotic cells. Figures show a representative experiment of three independent experiments. *P<0.05 and **P<0.01 compared with As3+ and As4S4 combination treated cells.
