  • 功能Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
  • 疾病相关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.
  • 序列相似性Belongs to the beta-2-microglobulin family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
  • 翻译后修饰Glycation of Ile-21 is observed in long-term hemodialysis patients.
  • 细胞定位Secreted. Detected in serum and urine.

Anti-beta 2 Microglobulin antibody [B2M-01] (Biotin) 图像

  • IHC image of beta 2 Microglobulin staining in human normal lung formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab21899, 10µg/ml, for 15 mins at room temperature and detected using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

These two monoclonals may be an effective pair but they have not been tested with each other in sandwich ELISA. My concern is whether or not the epitope (the binding site) that the beta 2 microglobulin antibody ab21899 recognizes is accessible if it is...
