Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. After reconstitution store at -20ºC. Avoid freeze / thaw cycles.

    pH: 7.20
    Constituents: 99.2% Phosphate Buffer, 0.88% Sodium chloride

  • Reconstitution
    Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 µg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

  • 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
    modifications

    Glycation of Ile-21 is observed in long-term hemodialysis patients.
  • Cellular localization

    Secreted. Detected in serum and urine.
  • Information by UniProt
