  • 应用说明
    Is unsuitable for IHC-P.
  • 靶标

    • 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.

    In review of the immunogen sequence used for creating ab75853 I see this sequence share only 69.2% identity with rabbit beta-2-microglobulin. Generally we do not expect reactivity below 80%. Overall I have found that the sequence homologies of human...
