Fig. 7. Confocal microscopy images for concentration-dependent H2O2-induced fluorescence in living HeLa cells using 2. (A) Cells were co-incubated with probe 2 (10 μM) and H2O2 (0, 50, 100 or 200 μM) for 1 h, washed and imaged. Scale bar, 10 μm. (B) Relative fluorescence intensity of images versus H2O2 concentration. N = 3 fields of cells, error bars are means ± sd. *P < 0.05; **P < 0.01.
