COX IV Antibody (YA867)

COX IV Antibody (YA867) is an unconjugated, mouse-derived, anti-COX IV (YA867) IgG1 monoclonal antibody. It can be used as a loading control antibody.

COX4I1, a vital constituent of the cytochrome c oxidase, serves as a pivotal component in the mitochondrial electron transport chain, culminating in oxidative phosphorylation. This respiratory chain encompasses three multisubunit complexes—succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII), and cytochrome c oxidase (complex IV, CIV)—that collaboratively facilitate the transfer of electrons from NADH and succinate to molecular oxygen. This intricate process generates an electrochemical gradient across the inner membrane, propelling transmembrane transport and fueling ATP synthase. Specifically, cytochrome c oxidase orchestrates the reduction of oxygen to water. The electron transfer from reduced cytochrome c in the intermembrane space involves intermediates, such as the dinuclear copper A center (CU(A)) in subunit 2 and heme A in subunit 1, ultimately converging at the active site in subunit 1—a binuclear center (BNC) comprised of heme A3 and copper B (CU(B)). The BNC efficiently reduces molecular oxygen to two water molecules, utilizing four electrons from cytochrome c in the intermembrane space and four protons from the mitochondrial matrix. COX4I1 thus plays a central role in energy metabolism, contributing to the intricate processes of oxidative phosphorylation.

• 
  Immunohistochemical analysis of paraffin-embedded human Pancreatic carcinoma‌ tissue using COX IV antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P81025, 1:100 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium.

• 
  Tyramide signaling amplification based immunofluorescence was performed on paraffin-embedded human ovarian carcinoma (sample 1) tissue using COX IV antibody. Antigen retrieval was performed in EDTA buffer pH 9.0 (95 °C, 20 min) followed by cooling to RT. Then incubated with primary antibody (HY-P81025, 1:100 dilution) at room temperature for 60 minutes and HRP conjugated secondary antibody for 10 minutes. Fluorescence was then developed with TSA520 . The tissues were counterstained with DAPI and mounted with Anti-fade mounting medium.
