We used in situ hybridization to specifically identify mitochondria in a series of formalin-fixed, paraffin-embedded oncocytic lesions. Digoxigenin- labeled DNA probes were generated by the polymerase chain reaction (PCR), with primers designed to amplify a mitochondrion-specific 154 BP sequence within the ND4 coding region. Probes were hybridized with mitochondrial DNA under stringent conditions. Oncocytes were strongly and consistently stained, reflecting the high copy number of mitochondrial DNA within these cells. Because of the presence of endogenous biotin within mitochondria, digoxigenin is preferable to biotin as a label for detection of mitochondria.
