Figure 3: Analysis of CAT (a), Cu/Zn-SOD (b), and GPX (c) activities and a representative gel of both enzyme activities by gel staining as described in Materials and Methods. (d) Representative Western blot. The band densities were analyzed by UVP image analyzer, and the results are reported as pixels. For loading control, another gel was dedicated to be stained by coomassie blue. For the gel activity staining, data are expressed as the mean ± SD ( different preparations from 4 different animals). For the GPX activity assessed by spectrophotometry (see Materials and Methods), data corresponds to mean ± SD of 6 different preparations from 6 different animals. compared to the control group and compared to the SF group.
