    The Cytochrome P450 (P450) superfamily of enzymes is one of three enzyme systems which metabolize the fatty acid arachadonic acid (AA) to regulators of vascular tone. P450 enzymes are monooxygenase enzymes which require several co-factors such as nicotinamide adenine dinucleotide phosphate (NADPH) and P450 reductase. There are over 200 known genes which encode P450s. Epoxygenases are those P450s which metabolize AA to epoxyeicosatrienoic acid (EETs) and omega-hydroxylases are those P450s which produce 19- and 20-hydroxyeicosatetraenoic acids (19- and 20-HETE). As well as fatty acid metabolism, P450s also metabolize many drugs and toxins. Cytochrome P450 3A4 is abundantly expressed in liver and small intestine and is inducible by barbiturates, glucocorticoids and rifampicin.

    Cytochrome P450 oxidase (commonly abbreviated CYP) is a generic term for a large number of related, but distinct, oxidative enzymes important in vertebrate physiology. The cytochrome P450 mixed-function monooxygenase system is probably the most important element of Phase I metabolism in mammals. P450s are membrane-bound, either in the inner membrane of mitochondria or in the endoplasmic reticulum of cells where they metabolise thousands of endogenous and exogenous compounds. In the liver, these substrates include toxins, drugs, and other unneeded and potentially harmful molecules. Humans have 18 families of cytochrome P450 genes and 43 subfamilies; the CYP1 family is involved in drug metabolism and includes 3 subfamilies, 3 genes and 1 pseudogene.

  • ab4227 used in Immunoprecipitation.
    The systems were cross-linked (X-L) with BS3, immunoprecipitated (IP) with ab4227, subjected to SDS-PAGE, and blotted with anti-CYP1A2.

    Each of the reconstituted systems was cross-linked with the water-soluble, homobifunctional cross-linking agent BS3, which reacts with primary amino groups. Each 100µl reaction mixture was treated with 1 mM BS3 for 2 minutes at 4 °C and then quenched with 96µl of ice-cold 2radioimmune precipitation buffer and 500 mM glycine and placed in an ice bath. Samples remained on ice for 15 minutes before the addition of 4µl of ab4227. Samples were then allowed to incubate for 2 hours on ice. At the end of the 2-hour incubation, 100µl of 25% (w/v) Protein G-agarose bead slurry was added, and each sample was rocked/incubated for 1 hour at 4 °C. Samples were spun for 10 seconds at 3500g, the supernatants were transferred to clean microcentrifuge (1.5-ml) tubes, and the bead pe
