Immunohistochemistry (PFA fixed): incubate antibody for 30 min RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95 degrees C followed by cooling at RT for 20 minutes.
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.
