Colocalization of SOD1 and mitochondrial signals in the
mouse spinal cord. Spinal cords from G93A mice were stained with anti-COX1
(green) and SOD1 (red) antibodies, and visualized using confocal imaging and 3
dimensional reconstruction. Notice that all mitochondrial signals overlap with
some SOD1 signals, while some SOD1 signals do not overlap with the
mitochondrial signal.
