靶标

  • 功能

    Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.

  • 疾病相关

    Defects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:241600]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.
    Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states. The capacity to assemble into amyloid fibrils is concentration dependent. Persistently high beta(2)-microglobulin serum levels lead to amyloidosis in patients on long-term hemodialysis.

  • 序列相似性

    Belongs to the beta-2-microglobulin family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.

  • 翻译后修饰

    Glycation of Ile-21 is observed in long-term hemodialysis patients.

  • 细胞定位

      IHC image of beta 2 Microglobulin staining in human normal lung formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab21899, 10µg/ml, for 15 mins at room temperature and detected using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Question

    I would like to try the ab218999 for immunoprecipitation, which is the working dilution range for this assay? Thanks,

    Answer

    Thank you for contacting us.

    When using ab21899 Anti-beta 2 Microglobulin antibody [B2M-01] (Biotin) in IP we can recommend a working range of 1-10 ug/ml. The exact concentration for your IP experiments should be within this range but could be outside of this and will need to be determined experimentally.

    Abcam also provides a number of products for use in IP such as our https://www.abcam.com/ab119211 ready to use protein gel stain, our https://www.abcam.com/index.html?pageconfig=resource&rid=15115#1 and our https://www.abcam.com/index.html?pageconfig=resource&rid=15115#2 . Our VeriBlot line only recognize native (non-reduced) antibodies and are recommended when the target of interest is <30kDa, whereas our Light Chain specific line do not recognize heavy-chains and are recommended when your protein of interest is >30kDa. All of our products are covered by our six month Abpromise guarantee and are fully supported by our scientific support staff. More information about these products can be found at the links below.

    Question

    Yes, I want to coat the plate with ab94886 in order to captureHLA-G onto the plate. Then I want to detect beta 2 microglobulin(because both proteins are ensemble together in the native form) withab21889.
    So, if I want to detect these two proteins, are these clones I chose the best for ELISA? (Specially for beta 2 microglobulin, as I saw there are two distinct clones both for ELISA)

    Answer

    These two monoclonals may be an effective pair but they have not been tested with each other in sandwich ELISA. My concern is whether or not the epitope (the binding site) that the beta 2 microglobulin antibody ab21899 recognizes is accessible if it is in an ensemble/complex with the HLA G. That is also the case for the other monoclonal, ab25160.

    A better choice may be a polyclonal antibody raised against full-length beta 2 microglobulin, which will recognize many epitopes, not just one. I suggest ab34678, a biotinylated rabbit polyclonal.

    Click here (or use the following: https://www.abcam.com/beta-2-Microglobulin-antibody-Biotin-ab34678.html).

    However, this has not been tested in sandwich ELISA with ab94886 either. We do not have any pairs that have been validated for sandwich ELISA but ab94886 and ab34678 are my recommendation. (Please note that these have only been tested against human samples).

    If you do decide to try these, we would be very interested in hearing about the result via our Abreview program. Details can be found here:
