Anti-POR antibodies are used in the immunodetection of the protein cytochrome p450 oxidoreductase. In humans, the canonical protein has a reported length of 677 amino acid residues and a mass of 76.7 kDa. Its subcellular localization is in the ER. It is notably widely expressed in many tissue types. A member of the NADPH--cytochrome P450 reductase protein family; Flavodoxin protein family; Flavoprotein pyridine nucleotide cytochrome reductase protein family, POR is known to be involved with the regulation of apoptosis. Synonyms for this target antigen include CYPOR, P450R, NADPH--cytochrome P450 reductase, NADPH--hemoprotein reductase, NADPH-dependent cytochrome P450 reductase, and CPR. POR gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 60 citations in the literature describe the use of POR antibodies in research. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
