Immunofluorescent analysis of Cytochrome P450 4A (green) showing staining in the cytoplasm and membrane of H-4-II-E cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Cytochrome P450 4A polyclonal antibody (Product # PA3-033) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a flourescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

PA3-033 detects cytochrome P450 4A (isoforms 1, 2, & 3) from human, feline, rabbit and rat tissues.
PA3-033 has been successfully used in Western blot, ICC/IF and IHC procedures. By Western blot, this antibody detects an ~50 kDa protein representing P450 4A in rat liver extract. Immunohistochemical staining of P450 4A in rat brain with PA3-033 results in perivascular and surrounding cortex staining.
The PA3-033 immunogen is a synthetic peptide corresponding to residues D(431) P S R F A P D S P R H S H S(445) of rat Cytochrome P450 4A.
The cytochrome P450 (P450) family 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 NADPH and P450 reductase. There are over 200 cDNA"e;s which encode P450 protein. Epoxygenases are those P450 proteins which metabolize AA to epoxyeicosatrienoic acid (EETs) and w-hydroxylases are those P450 proteins which produce 19- and 20-hydroxyeicosatetraenoic acids (19- and 20-HETE). 20-HETE is converted from AA by the 4A family of P450 proteins which includes at least 8 different, though closely related isoforms. 4A1, 4A2, & 4A3 have been cloned from liver, kidney and testis and have been detected in renal, hepatic & brain microvessels.
