β-2-microglobulin is part of the human leukocyte antigen, where it represents the light chain. It is expressed on cell membranes and is made up of 99 amino acids. β-2-microglobulin is part of the immunoglobulin superfamily. β−2-Microglobulin is a membrane glycoprotein of mammalian nucleated cells including lymphocytes.
Monoclonal anti-β-2-Microglobulin (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.
Immunogen
human β2-microglobulin and a lysate of a lymphoblastoid cell line.
Application
Monoclonal Anti-β2-Microglobulin antibody produced in mouse has been used in ELISA and immunofluorescent labelling.
Biochem/physiol Actions
β-2-microglobulin acts as a tumor marker and has been shown to be associated with dialysis-related amyloidosis. It may function as a structural part of the MHC Class I molecule.
Microglobulin may be elevated in the serum or urine of patients with systemic lupus erythematosus (SLE), rheumatoid arthritis, metal toxications, some viral infections and possibly malignant disorders and AIDS.

Level and persistence of antigenic peptides presented by APCs on MHC class I (MHC-I) molecules influence the magnitude and quality of the ensuing CTL response. We recently demonstrated the unique immunological properties conferred on APCs by expressing beta2-microglobulin (beta2m) as

Heterodimers of MHC class I glycoprotein and beta(2)-microglobulin (beta(2)m) bind short peptides in the endoplasmic reticulum (ER). Before peptide binding these molecules form part of a multisubunit loading complex that also contains the two subunits of the TAP, the transmembrane

The acute-phase proteins serum amyloid A protein (SAA) and secretory phospholipase A2 (sPLA2) are simultaneously expressed during inflammatory conditions. SAA associates with high-density lipoprotein (HDL) altering its physicochemical composition. We found that purified acute-phase SAA, but not the constitutive form
