  • Description
    Mouse monoclonal [B2M-01] to beta 2 Microglobulin (PerCP/Cy5.5®)
  • Host species
  • Conjugation
    PerCP/Cy5.5®. Ex: 482nm, Em: 690nm
  • Specificity
    ab157311 reacts with beta 2 Microglobulin associated with cell-surface MHC Class I molecules and other membrane antigens as well as with soluble beta 2 Microglobulin. beta 2 Microglobulin is expressed on lymphocytes, thymocytes, monocytes, granulocytes, platelets, endothelial cells and epithelial cells. It is absent on erythrocytes.

Our Abpromise guarantee covers the use of ab157311 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Flow Cyt Use 4µl for 106 cells. (or 100 µl of whole blood).
IP Use at an assay dependent concentration. Application note: ab157311 coprecipitatesbeta 2 Microglobulin (12 kDa) and HLA antigens (45 kDa) from the lysates of Human lymphoid cells.
WB Use a concentration of 2 - 4 µg/ml. Predicted molecular weight: 14 kDa. Application note: Both reducing and non-reducing conditions.
IHC-P Use a concentration of 10 µg/ml.
ELISA Use at an assay dependent concentration.
RIA Use at an assay dependent concentration. Application note: The dissociation constant of ab157311 is 1.5 x 10-8 mol/l as determined by competitive RIA.


  • Function
    Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
  • Involvement in disease
    Defects 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 similarities
    Belongs 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 localization
    Secreted. Detected in serum and urine.
