Figure 4

The mitochondrial membrane potential of SP2/0 cells detected by JC staining with flow cytometry. A: Fluorescence intensity detected by channel 1 (FL1); B: Fluorescence intensity detected in channel 2 (FL2); C: Mitochondrial membrane potential was expressed as the ratio of FL-2/FL-1. (a) Untreated control cells; (b) Cells treated with hypericin at 0.025 μM; (c) Cells treated with hypericin at 0.05 μΜ. **P < 0.05 compared with untreated controls.
