    beta 2 Microglobulin 一次抗体 製品一覧
  • 製品の詳細
    Mouse monoclonal [B2M-01] to beta 2 Microglobulin
  • 特異性This antibody reacts with beta-2-microglobulin, associated with cell-surface MHC Class I molecules and other membrane antigens as well as with soluble forms of beta-2-microglobulin. The antibody detected beta-2-microglobulin in U-937 and RAJI cell lines in WB in non reducing conditions however failed to detect a band in JEG-3 and A431 cell lysates. All lysates gave a signal in direct ELISA.

Our Abpromise guarantee covers the use of ab759 in the following tested applications.

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

アプリケーション Abreviews 特記事項
ELISA Use at an assay dependent concentration.
Flow Cyt Use at an assay dependent concentration.
IP Use at an assay dependent concentration.
RIA Use at an assay dependent concentration. Dissociation constant of the antibody-soluble b2-microglobulin is 1.5 x 10-8 mol/l as determined by competitive RIA.
WB Use a concentration of 2 µg/ml. Use under non reducing condition. Detects a band of approximately 13 kDa (predicted molecular weight: 13 kDa). Use under non reducing conditions. Incubate overnight. Block with 5%milk for 2hrs.


  • 機能Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.
  • 関連疾患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.
  • 配列類似性Belongs to the beta-2-microglobulin family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
  • 翻訳後修飾Glycation of Ile-21 is observed in long-term hemodialysis patients.
  • 細胞内局在Secreted. Detected in serum and urine.
