特性

Our Abpromise guarantee covers the use of ab83931 in the following tested applications.

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

  • 生理活性

    The ED50 of BAFF Receptor – Fc Chimera is typically 0.02-0.08 μg/ml as measured by its ability to neutralize BAFF-mediated proliferation of the RPMI 8226 cell line.

  • アプリケーション

    SDS-PAGE

  • 精製度
    > 95 % SDS-PAGE.

  • 製品の状態
    Lyophilised
  • Concentration information loading...

前処理および保存

  • 保存方法および安定性

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

    Preservative: None
    Constituents: 10% Trehalose, 1% Human serum albumin

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • 再構成
    It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. Following reconstitution short-term storage at 4°C is recommended, with longer-term storage in aliquots at -18 to -20°C. Repeated freeze thawing is not recommended.

  • 機能
    B-cell receptor specific for TNFSF13B/TALL1/BAFF/BLyS. Promotes the survival of mature B-cells and the B-cell response.
  • 組織特異性
    Highly expressed in spleen and lymph node, and in resting B-cells. Detected at lower levels in activated B-cells, resting CD4+ T-cells, in thymus and peripheral blood leukocytes.
  • 関連疾患
    Defects in TNFRSF13C are the cause of immunodeficiency common variable type 4 (CVID4) [MIM:613494]; also called antibody deficiency due to BAFFR defect. CVID4 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low.
  • 配列類似性
    Contains 1 TNFR-Cys repeat.
  • 細胞内局在
    Membrane.

画像

  • Lane 1 – MW markers; Lane 2 – ab83931; Lane 3 – ab83931 treated with PNGase F to remove potential N-linked glycans; Lane 4 – ab83931 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. 3 μg of protein was loaded per lane. Gels were stained with Coomassie G250.
    Drop in MW after treatment with PNGase F indicates the presence of N-linked glycans. A subsequent drop in MW after treatment with a glycosidase cocktail indicates O-linked glycans are also present. Additional high MW bands in lane 4 are glycosidase enzymes.
  • A sample of ab83931 without carrier protein was reduced and alkylated. 40 μg of protein was loaded, focused on a 3-10 IPG strip then run on a 4-20% Tris-HCl 2D gel. Spot train (Deep Purple™ stained) indicates presence of multiple glycoforms of BAFF Receptor - Fc Chimera. Spots within the spot train were cut from the gel and identified by protein mass fingerprinting as BAFF Receptor - Fc Chimera.
  • Post-translational modifications result in protein heterogeneity. The densitometry scan demonstrates the purified human cell expressed protein exists in multiple glycoforms, which differ according to their level of post-translational modification.
