The distribution of respiratory chain complexes in beef heart and human muscle mitochondria has been explored by immunoeledron microscopy with antibodies made against beef heart mltochondriai proteins in conjundion with protein A cofloidai gold (l2nm particles). The antibodies used were made against NADH-conezyme Q reductase(complex I), ubiquinol-cytochrome-c-oxldoreductase (complex III) and cytochrome-c-oxidase(complex IV). Labeling of bed heart tissue with any of these antihodies gave gold particles randomly distributed along the mitochondrial inner membrane. The labeling of muscle tIssue mitochondria from a patient with a mitochondrial myopathy localized by biochemical analysis to complex III was quantitated and compared with the labeling of human control muscle tissue mitochondria. Four kinds of morphological changes in the mitochondrial fine strudure in the myopathy patient tissue have been found; paracrystalline inclusions consistIng of densely packed multi- lamellar structures, globular crystalline inclusions with high electron density, multilamellar strudure inclusion body(compadly and irregularly arranged concentric whirl shaped cristae)and golbular cyrstalilne inclusions located in the center of the whirl shaped cristae. Compex I and cytochrome-c-oxldase antihodies reacted to the same level in the mitochondria containing the crystalline inclusions and control mitochondria. Antibodies to complex III reacted very poorly to the mitochondria containing the crystalline Inclusions but strongly to control mitchondria. The globular crystalline inclusions in the mitochondria are not reacted antibodies to respiratory chain complexes.
