摘要：

Defects in mitochondrial oxidative phosphorylation (OXPHOS) are a frequent cause of severe inherited metabolic disorders and also contribute to aging. The OXPHCS system constitutes five multi-subunit complexes embedded in the mitochondrial inner membrane. Correct function of this system requires proper assembly of the similar to 80 proteins in the complexes, as well as numerous assembly factors. Blue native electrophoresis has become a crucial tool to investigate OXPHOS-related defects in mitochondrial disease patients. In addition, OXPHOS-assembly profiles can be obtained by two dimensional blue native/SDS gel electrophoresis, which provides additional information for identifying disease-causing mutations and insight in the role of specific proteins in the biogenesis of the OXPHOS system. Here we provide a practical guide on how to set-up the basic technique to study OXPHOS defects in patient-derived cells and tissues. (C) 2008 Elsevier Inc. All rights reserved.
