Anti-beta2-microglobulin antibodies are used for the immunodetection of the protein encoded by the B2M gene. In humans, the canonical protein has a reported length of 119 amino acid residues and a mass of 13.7 kDa. It is known to be a secreted protein. A member of the Beta-2-microglobulin protein family, it is a known component of the class I major histocompatibility complex (MHC). Post-translational modifications have been described, including glycosylation. The gene encoding this protein is implicated in Immunodeficiency. Other names for this target antigen include beta chain of MHC class I molecules, beta-2-microglobin, and IMD43. Gene orthologs have been identified in the mouse, rat, frog, chimpanzee and chicken species. Western Blot is the most common application for the beta2-microglobulin antibodies listed below. ELISA and Immunohistochemistry are also common applications.
