We have examined the ultrastructure and the protein content of native matrix granules (NMG) in rat heart mitochondria, by postembedding immunocytochemistry. Cytochrome c oxidase was found to be present in these granules. It is believed that these granules contain incomplete inner mitochondrial membrane fractions, which can be incorporated in the membrane after stimulation of the metabolism.
