ターゲット情報

  • 機能

    Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. The enzyme also hydroxylates etoposide.

  • 組織特異性

    Expressed in prostate and liver. According to some authors, it is not expressed in brain (PubMed:19094056). According to others, weak levels of expression are measured in some brain locations (PubMed:19359404 and PubMed:18545703). Also expressed in epithelium of the small intestine and large intestine, bile duct, nasal mucosa, kidney, adrenal cortex, epithelium of the gastric mucosa with intestinal metaplasia, gallbladder, intercalated ducts of the pancreas, chief cells of the parathyroid and the corpus luteum of the ovary (at protein level).

  • 配列類似性

    Belongs to the cytochrome P450 family.

  • 翻訳後修飾

    Polyubiquitinated in the presence of AMFR and UBE2G1 and also STUB1/CHIP and UBE2D1 (in vitro).

    Question

    Hi, I have a question about ab3572. I performed western blot with it and got two bands which have similar size. I suppose that these are CYP3A4 and 3A5. There was no comment about cross-reactivity with CYP3A5 in the datasheet. Does ab3572 have crosse-reactivity with CYP3A5? Even if there's no data about cross-reactivity, can we expect it? I am looking forward to your kind reply. Thanks.

    Answer

    Thank you for your enquiry. I can confirm that this product detects cytochrome P450 3A4 from human and rat tissues and cells. Unfortunately, we do not have any information or data showing cross reactivity with 3A5 but it may detect, to a lesser extent, other P450 isoforms. I am sorry there is not much information on the matter but you have any other questions, please do not hesitate to contact me.

    Question

    What is the concentration of the current lot of ab3572?

    Read More
    Answer

    I was informed by the originator of the antibody that the concentration was not determined, quite surprisingly. They predict the concentration to be around 1mg/ml. I'm sorry I couldn't help you more. Please do not hesitate to contact me again if I can be of further assistance,

    Question

    Customer has said that there is no 3A4 present in rat - do you have any information regarding this?

    Read More
    Answer

    It is true that rats do not express 3A4. This is a human specific CYP. Rats do express others in the CYP family which this antibody cross-reacts with since the immunogen was full length human P450 3A4 fusion protein. That explains the cross-reaction with other rat CYP families (only we don't know which exact one!). If you have any more questions, please contact us again.

    Question

    1. more bands 2. rat liver whole cell lysates 3. 50 micro grams 4. i used three different protease inhibitors and used sonication 5. no i didnt heat the samples 6. primary antibody raised in rabbit 7. 1 in 2000 8. incubated over night. did five to six washes 9. the secondary antibody concentrations were tested from 1 in 2000 to 1 in 10,000. 10. no it is not due to the secondary antibody as they look were no bands in secondary antibody control 11. incubated for one hour in secondary antibody 12. we are using horse raddish peroxidase and taking the pictures in x ray film 13. yes i did a column as control in which i didnt add the primary antibody 14. i tried different concentrations of secondary

    Answer

    Thank you very much for the details that you have provided and for your patience. What was the lot number that you received? Why did you not heat the samples to denature the proteins? In addition to the non-specific bands that you are seeing, did you see the expected band at 46 kDa? I can offer you a replacement vial or a refund, please send me the Abcam order number of purchase order number that was used.

    Question

    Customer would like to know the concentration of the batch currently in stock.

    Answer

    Thank you for your enquiry. We did not perform experiments to determine the approximate concentration for these lots. It is purified IgG, and we don't know how much of it is specific for Cytochrome P450 3A4. We would recommend using this antibody at 1/2000 dilution for Western blot application.

    Question

    I am working on fescue toxin in rats liver. I am plannig for immuno histo chemistry in around 72 samples. I was strongly suggested to use the antibodies from ur company. so i went to abcam website. in that i saw that this antibody is tested only for WB. so i am not sure if i can use this for IHC. so i request you to send me a very small quantity of the CYTOCHROME P 450 3A4 (AB3572) sample. so that i can test run for a couple of samples.

    Question

    I am writing to you with reference to your antibody to Cytochrome P450 3A4 (ab3572). I need to screen quite large numbers of transgenic cyp3A4 regulatable cells that I am developing and consequently will need an antibody to cyp3A4. Before I purchase the antibody, I will need to know if it is applicable to my research use. Therefore would it be possible to send me a very small quantity (5 or 10microL) of your anti cyp3A4 for me to test prior to purchase? Many thanks for your time.

    Answer

    We do not routinely offer free or trial sized samples for testing purposes. Our policy at Abcam is that if an antibody does not work as specified on the datasheet, we will offer a replacement or reimbursement. This antibody has been tested in Western Blotting and cross reacts with human and rat. If you plan to use the antibody in an application other than Western Blotting, please let us know and I will look into offering you a discount on your first vial.
