K₅BW₁₂O₄₀ Induces the Apoptosis of A549 Cells by Regulating Caspase-3

Figure 2

Polyoxometalate K₅BW₁₂O₄₀ promotes the apoptosis of A549 cells. (a) The image of A549 cells. (b) A549 cells were treated with K₅BW₁₂O₄₀ for 48 h and then stained using the Annexin V-FITC/PI detection kit and detected by FCM. Annexin V-FITC single positive cells are early apoptotic cells, Annexin V-FITC and PI double positive cells are necrotic or late apoptotic cells, and PI single positive cells are naked nuclear cells.
