Fumarase, heat shock protein-60 (HSP60) and succinic dehydrogenase (SDH) immunoreactivity in the human kidney. All three antibodies labelled mitochondria in the proximal convoluted tubule, in the glomerulus positive immunoreactivity was only found to a very limited extend and individual mitochondria could only be detected at very high-power magnification (data not shown). Isotype controls did not show any immunoreactivity. The scale bar represents 50 µm on the left side (100 µm at HSP60) and 50 µm on the right side
