ターゲット情報

  • 機能

    Protein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN.

  • 関連疾患

    Defects in PTPRC are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (T(-)B(+)NK(+) SCID) [MIM:608971]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development.
    Genetic variations in PTPRC are involved in multiple sclerosis susceptibility (MS) [MIM:126200]. MS is a neurodegenerative disorder characterized by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in third or fourth decade with intermittent progression over an extended period. The cause is still uncertain.

    Question


    Thanks for your reply. What is the difference when some antibodies say
    tested for ICC/IF and some just say ICC? I am using sections of a
    paraffin-embedded sample, incubating them with the primary antibodies
    I mentioned, using a fluorescent-tagged secondary antibody, mounting
    the samples, and then using a fluorescence microscope to image the
    samples.

    Read More
    Answer


    IF by definition refers to any antibody application that utilizes fluorescence as the detection method. Thus, technically ICC and IF are one in the same, and you could argue that IHC is also a form of IF.

    For the purposes of searching for products on our website, we distinguish those antibodies that have been tested in IHC with IHC followed by a letter designation (P-paraffin embedded sections, Fr-frozen sections, FoFr-formaldehyde fixed frozen sections). If an antibody has ICC or ICC/IF listed under tested applications they are the same thing and guaranteed to work in immunocytochemistry.

    It sounds like you are performing IHC-P, immunohistochemistry on paraffin embedded sections; thus, all three antibodies that you identified, ab53003, ab8216, and ab111250 are tested and guaranteed to detect their respective targets via IHC-P in human samples. As stated in our AbPromise guarantee, we are happy to provide scientific support, replacement or refund should these products if they do not perform as indicated on the datasheet.

    Answer

    Thank you for your enquiry. I am sorry to hear that you have been having difficulties with ab8216. I have read your technical questionnaire and I have a few comments. You are using an extraction protocol that I would advise: RIPA buffer. I also consider your choice of a positive control good in the form of human tonsil. I would not recommend using as much as 100ug in western blotting. However, given that you are obtaining no signal whatsoever, please can you tell me whether you have confirmed the successful transfer of your blot by Ponceau S. Also can you tell me whether you have confirmed the integrity of your lysate preparation using an alternative CD antiserum using these conditions. I look forward to hearing from you.

    Question

    I bought a cd45 antibody (ab8216) a few weeks ago. Unfortunately it does not work for Western Blot. The datasheet says that it should work for this technique. Could you please help me with that problem because I have already tried different concentrations and treatments, as well as the standard abcam protocol. Please answer me as soon as possible.

    Read More
    Answer

    I am sorry to hear that you have been experiencing problems with ab8216 in Western blotting. Often it is possible to make suggestions that help resolve problems. We will happily offer technical support and in the event that a product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 90 days of purchase), and if it appears that the antibody is at fault, a credit note/refund will be offered. Below I enclose a link to a questionnaire which will help you put your protocol information together very easily so we can look into the details of the experiment and provide some help. Thank you, and we look foward to hearing from you. https://www.abcam.com/index.html?section=western&pageconfig=technical&intAbID=8216&mode=questionaire

    Question

    What is the epitope recognized by this antibody? Does it recognize any fragments less than the expected size of the protein? I am interested in studying these cleavage fragments.

    Read More
    Answer

    We do not know the epitope or if this antibody recognizes any fragments less than the expected size of the protein. We do not have access to the original WB data. We did not perform such a study, and most likely, if we did and saw any smaller fragments, we would consider it as non-specific proteolytic cleavage during sample preparation rather then as a result of some biological process in a cell. Moreover, the major bands migrate between 180-220 kDa, so any cleavage fragment would presumably be lost due to the low density of gel used for LCA isoforms (so the fragments would migrate with the front of the gel). In short, you should test this hypothesis in your particular experimental setup. If you have any additional questions, please contact us again.

    Question

    Regarding a previous enquiry - could I use the mouse monoclonal antobody on paraffin-embedded mouse tissue in combination with the DAKO animal research kit (for mouse monoclonal antibodies on mouse tissue)? Or is there any anti-CD45 antibody suitable for paraffin-embedded mouse tissue?

    Read More
    Answer

    ab8216 has not been tested in mouse, so we have no further information on this. We have several CD45 antibodies so I suggest that you conduct a search through the Abcam Website. I also recommend that you should click on the links “Product Reviews” and “Technical Enquiries” both accessible via the green menu bar on the datasheet. Here you will find customer reviews and past questions and answers specifically relating to that product. If you cannot find what you are looking for within the Abcam catalog, I suggest that you click on the link to "The World's Antibody Gateway". The World's Antibody Gateway is a free search engine service provided by Abcam to help you to quickly find the antibodies that you are looking for.

    Question

    I am looking for an anti-CD45 antibody that is reactive with sheep tissue (prefaerably paraffin embedded tissues). My questions are: 1. Is ab8216 reactive with sheep tissue or is it likely to be on the basis of between species homology. 2. If not, can you recommend an antibody that does work on sheep tissue. Many thanks

    Read More
    Answer

    This antibody has not been tested for cross reactivity with sheep. As noted on the datasheet, for immunohistochemistry, no treatment of parrafin sections neccessary. I suggest that you examine the degree of sequence homology between human and sheep CD45. We do not have an antibody agaisnt CD45 that has already been tested for cross reactivity with sheep, but I suggest that you conduct a search through the Abcam home page, and click on the link in the yellow menu bar to "The World's Antibody Gateway" to determine whether any other companies stock such an antibody. The World's Antibody Gateway is a free search engine service provided by Abcam to help you to quickly find the antibodies that you are looking for.

    Question

    Hi, May I use this antibody on mouse tissue? Lisa

    Read More
    Answer

    No. Even if this antibody did recognise mouse CD45, the antibody has been raised in mouse, therefore the anti mouse secondary would non-specifically bind to the tissue leading to high background staining. At current we do not stock an antibody towards CD45 that has been raised in any other species.
