Rabbit polyclonal antibodies to Beta-2-Microglobulin

• Catalog Number: orb2284544
• Category: Antibodies
• Description: Beta-2-microglobulin (B2M) is a 12-14 kDa protein that is a subunit of the major histocompatibility complex (MHC) class I. Human beta 2 Microglobulin associated with HLA Class I antigens are expressed on many types of cells including lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells, and epithelial cells, but is absent on erythrocytes. Beta-2 microglobulin is also found in free form in the plasma. The amino acid sequence of Beta-2-microglobulin is homologous to the constant regions of immunoglobulin heavy and light chains, with a predominantly beta pleated sheet structure. The protein is ubiquitously expressed in the cytoplasm, and is involved in antigen processing and presentation. Beta-2-microglobulin also plays a role in TCR signaling, and downstream signaling in naive CD8+ cells. Beta 2-microglobulin is encoded by the B2M gene located on chromosome 15. A mutation in the Beta-2-microglobulin gene has been shown to result in hypercatabolic hypoproteinemia. Levels of beta 2 microglobulin can be used to assess renal function in kidney transplant recipients. Beta-2-microglobulin that protein can be used as a prognostic marker for HIV infection.

Western blot demonstrating our polyclonal detecting recombinant human Beta-2 Microglobulin (21-119 of P61769) at 1 in 2000 dilution. Lane 1: Marker; Lane 2: β2M (1ng); Lane 3: β2M (5ng); Lane 4: β2M (10ng); Lane 5: β2M (50ng).

ELISA Plates were coated with 0.6 µg/mL human recombinant Beta-2-microglobulin, rabbit anti-Beta-2-microglobulin was added at different concentrations and detected with an anti-rabbit HRP.
