Target Information 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. 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. β2 microglobulin also known as B2M is a component of MHC class I molecules, MHC class I molecules have α1, α2, and α3 proteins which are present on all nucleated cells (excludes red blood cells).

Beta-2-microglobulin is a LMW (17 kDa) ubiquitously expressed protein and a component of the major histocompatibility class (MHC) I molecule family. It is produced at a constant rate and freely filtered by the kidney. Beta-2 microglobulin (B2m) is the 11.8 kDa light-chain moiety of major histocompatibility complex class I (MHC I) present on the surface of nearly all nucleated cells MHC I functions immunologically in antigen presentation to cytotoxic T cells Beta-2 microglobulin (b2m) is a naturally occurring protein in the human body. It is one of two polypeptide chains that make up the structure of a major histocompatibility complex (MHC) Class I molecule. Certain characteristics of b2m make it suitable for detecting tumor cells, especially in blood Beta-2-Microglobulin, Urine - Beta-2-Microglobulin (B2M) is a low molecular weight protein that forms the light chain component of the histocompatibility antigen. It is synthesized by all nucleated cell types.

May 07, 2020 Feb 24, 2021 Nov 20, 2009 MHC class I molecules and beta (2)-microglobulin (beta (2)m) are membrane glycoproteins that present peptide Ags to TCRs, and bind to inhibitory and activating receptors on NK cells and other leukocytes. They are involved in the discrimination of self from non-self. β2-microglobulin (β2M) is a 12 kD nonpolymorphic Ig like protein. It is a non-membrane-anchored glycoprotein and is noncovalently associated with 39-44 kD polymorphic heavy chains of MHC class I molecules to form HLA class I antigen complex. The beta 2-microglobulin dissociation rate is an accurate measure of the stability of MHC class I heterotrimers and depends on which peptide is bound. J Immunol. 1992; 149(6):1896-1904.
