Purification and analysis of mitochondrial membrane proteins on nondenaturing gradient polyacrylamide gels

Purification and analysis of mitochondrial membrane proteins on nondenaturing gradient polyacrylamide gels

D R Kuonen et al. Anal Biochem. 1986 Mar.

Abstract

A nondenaturing gradient polyacrylamide gel electrophoresis method is described for the resolution of membrane proteins. Bovine heart inner mitochondrial membranes were solubilized in Triton X-100 and individual complexes were identified by staining for activity and protein. Succinate dehydrogenase was isolated by band excision and shown by electrophoresis under denaturing conditions to be highly purified. In addition, the electrophoretic transfer of NADH dehydrogenase to nitrocellulose was demonstrated. The enzyme was identified on the resulting blot by activity staining and the binding of monospecific antibodies.
