MnSOD mimic eliminates intracellular superoxide radical and H₂O₂ levels. (A) Representative images of laser scanning confocal microscopy. Arrows indicate red fluorescence representing the presence of intracellular superoxide radical. (B) Representative images of laser scanning confocal microscopy. Green fluorescence represents intracellular H₂O₂ levels. (B‐A) Cells treated with PBS; (B‐B) cells treated with 5 μM MnTm4PyP before H₂O₂ (100 μM) exposure for 2 h; (B‐C) cells treated with 100 μM H₂O₂ for 2 h; (B‐D) 0 Quantification of fluorescence intensity from mean ± SD, (n = 6). **P < 0.01 compared with the H₂O₂ group.
