Anti-beta 2 Microglobulin antibody [B2M-01] (Phycoerythrin) (ab49424)


  • Product nameAnti-beta 2 Microglobulin antibody [B2M-01] (Phycoerythrin)
    See all beta 2 Microglobulin primary antibodies
  • Description
    Mouse monoclonal [B2M-01] to beta 2 Microglobulin (Phycoerythrin)
  • ConjugationPhycoerythrin. Ex: 488nm, Em: 575nm
  • SpecificityThis antibody reacts with beta 2 microglobulin (b2M) associated with cell-surface MHC Class I molecules and other membrane antigens as well as with soluble beta 2 microglobulin. Beta 2 mircoglobulin is a 12 kDa Ig like glycoprotein expressed on lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells and epithelial cells. It is absent on erythrocytes.

Flow Cyt Use a concentration of 5 µg/ml.


  • FunctionComponent of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
  • Involvement in diseaseDefects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:241600]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.
    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.
  • Sequence similaritiesBelongs to the beta-2-microglobulin family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
  • Post-translational
    Glycation of Ile-21 is observed in long-term hemodialysis patients.
  • Cellular localizationSecreted. Detected in serum and urine.
