Figure 5: (a) Changes in immunofluorescence of MitoSOX and Prx 3 after the treatment of DETC, SOD, Rotenone, and Antimycin A. The cells were stained with specific antibodies of Prx 3 protein (green) and incubation with MitoSOX (red); nucleus was dyed with Hoechst (blue). Scale bar = 50 μm. (b) Prx 3 and MitoSOX fluorescence intensity (A, B) under different treatment. Data were analyzed by mean ± SD (). versus control group. versus KI group.
