Mitochondrial C-I assembly and activity analysis. (A) BN-PAGE was performed in the isolated mitochondrial preparation of cultured cells. (B) C-I activity was measured using in gel C-I activity assay. Relative band intensities of C-I on (C) BN-PAGE and (D) in-gel assay were quantitated using ImageJ and normalized with total mitochondrial protein loaded (80 µg). (E) Equal loading of mitochondrial proteins is shown by immunoblotting results of an aliquot of the same samples used for BN-PAGE/in-gel assay, with mitochondrial marker protein VDAC. C-, complex; VDAC, Voltage-dependent anion channel; BN-PAGE, Blue native polyacrylamide gel electrophoresis.
