Anti-CYP2J2 antibodies are used in the immunodetection of the protein cytochrome P450 family 2 subfamily J member 2. In humans, the canonical protein has a reported length of 502 amino acid residues and a mass of 57.6 kDa. Its subcellular localization is in the ER. It is reported to be highly expressed in the heart, present at lower levels in the liver, kidney and skeletal muscle. A member of the Cytochrome P450 protein family, CYP2J2 is a cytochrome P450 monooxygenase involved in the metabolism of polyunsaturated fatty acids (PUFA) in the cardiovascular system. Synonyms for this target antigen include CYPIIJ2, cytochrome P450 2J2, albendazole monooxygenase (hydroxylating), albendazole monooxygenase (sulfoxide-forming), and CPJ2. CYP2J2 gene orthologs have been reported in the mouse, rat and chimpanzee species. A number of CYP2J2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
