Immunofluorescence analysis of OXPHOS COMPLEX IV SU (MTCO2) was performed using 90% confluent log phase Hep G2 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with MTCO2 (12C4F12) Mouse Monoclonal Antibody (A-6404) at 2µg/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing membrane localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

Cytochrome c oxidase is the fourth complex in the respiratory chain and is responsible for catalyzing the conversion of O2 to H2O. Subunit 2 of the cytochrome c oxidase complex combines with two other subunits (1 and 3) to form a core protein structure that performs many functions of the enzyme. The metallic copper center of this subunit transfers electrons to the heme center of subunit 1, which results in the movement of electrons from cytochrome c to the heme A3 and copper B metallic center of complex IV. Defects in subunit 2 of cytochrome c oxidase can result in COX deficiency, which causes a wide range of symptoms from local myopathy to multiple system pathologies that begin between infancy and adulthood. Abnormalities in this subunit are also associated with tumor development.
