Precautions | Beta-2 Microglobulin (Renal Failure & Tumor Marker) Antibody - With BSA and Azide is for research use only and not for use in diagnostic or therapeutic procedures. |
Name | B2M (HGNC:914) |
---|---|
Function | Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. Exogenously applied M.tuberculosis EsxA or EsxA-EsxB (or EsxA expressed in host) binds B2M and decreases its export to the cell surface (total protein levels do not change), probably leading to defects in class I antigen presentation (PubMed:25356553). |
Cellular Location | Secreted. Cell surface. Note=Detected in serum and urine (PubMed:1336137, PubMed:7554280). {ECO:0000269|PubMed:7554280, ECO:0000269|Ref.6} |

Background
Recognizes a protein of 12kDa, identified as ļ� �ļ€ �ļ€ �microglobulin. Beta-ļ€ �-microglobulin non-covalently associates with the 44kDa ļ�� chain to form the HLA Class I antigen complex. Humanļ€ļ� �eta-ļ€ �-microglobulin associated with HLA Class I antigens is expressed on many types of cells including lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells, and epithelial cells. It is absent on erythrocytes. This MAb is specific to humanļ€ļ� �ļ€ �-microglobulin and does not react with non-human primate cells. This antibody reacts with all cell types excluding erythrocytes. The detection of Ć�2Āmicroglobulin in body fluids has been used as a tumor marker and for monitoring patients with HIV infection.
