Fig 1: Protein abundance of SOD1 (A) and SOD3 (B) in saphenous arteries of adult and young rats. Data are normalized to GAPDH. The mean value of SOD1 or SOD3 protein content in the adult group is taken as 100%; n is the number of animals. * p < 0.05 (unpaired Student’s t-test). The whole-length Western blot membranes are shown in Supplemetary Materials (Figure S1).
