Mitochondria isolation from kidneys of Sham and CLP groups was performed using sucrose containing buffer as described previously [18 (link),19 (link)]. Mitochondrial complexes were extracted from the isolated mitochondria (250 μg) using 10% n-dodecyl-β-D-maltoside and 0.5 M aminocaproic acid (detergent/protein ratio, 2.5 g/g). The mitochondrial extracts (40 μg) were then resolved in a BN-PAGE gel [19 (link),20 (link)] followed by western blotting with 4-HNE (Abcam, 1:500) and Core-2 (Abcam,#ab14745;1:1000).
