Salvianolic acid B protects hepatocytes from H2O2 injury by stabilizing the lysosomal membrane

Figure 5 Effect of Sal B on the leakage of CatB/D into the cytosol. A and B: CatB/D levels in the cytosol/whole lysate were measured by western blot; C and D: Quantitative analysis of optical densities of CatB/D in the cytosol/whole lysate and normalized to the expression of β-actin; E: CatB activity analysis was performed with chemiluminescence detection. (^bP < 0.01 vs Con; ^dP < 0.01 vs H₂O₂).
