Figure 2. Mitochondrial localization of ATP synthase visualized by immunocytochemistry using anti-ATP synthase subunit beta mAb 3D5AB1 (MS503). Cultured human fibroblasts were fixed, permeabilized and then labeled with MS503 followed by an AlexaFluor® 488-conjugated-goat-anti-mouse IgG1 isotype specific secondary antibody (2 µg/ml).
