Invitrogen™ NOX2 Monoclonal Antibody (54.1)

Descripción

This antibody is specific for NOX2/gp91phox (aa 382-389, PKIAVDGP). The immunogen was prepared using partially purified human neutrophil flavocytochrome b (heparin Ultrogellectin affinity purification in Triton X-100). Western blot results show a band at 65 kDa, which matches the predicted molecular weight. For IHC applications, perform heat-mediated antigen retrieval with citrate buffer, pH 6, prior to staining.

Mox1 and the glycoprotein gp91-phox are largely related proteins that are essential components of the NADPH oxidase. The superoxide-generating NADPH oxidase complex expresses in phagocytes, neuroepithelial bodies, vascular smooth muscle cells, and endothelial cells. It includes a membrane bound flavocytochrome containing two subunits, gp91-phox and p22-phox, and the cytosolic proteins p47-phox and p67-phox. The p22- and gp91-phox subunits also function as surface O2 sensors that initiate cellular signaling in response to hypoxic conditions. Mox1 and gp91 contain identical C-terminal sequence identity, yet possess distinct expression patterns. gp91-phox expresses in eosinophils, neutrophils, monocytes, and B-lymphocytes, whereas Mox1 is predominantly detected in the colon, with low expression in the uterus and prostate.
