Figure 4. Mitochondrial localization of complex IV in normal human fibroblasts visualized by immunocytochemistry using anti-complex IV subunit IV mAb 10G8D12C12 (MS408). Cultured human embryonic lung-derived fibroblasts (strain MRC5) were fixed, permeabilized and then labeled with MS408 (10 µg/ml) followed by an AlexaFluor® 488-conjugated-goat-anti-mouse IgG2a isotype specific secondary antibody (1 µg/ml)
