  • Target

    • Function

      Cytokine that binds to TNFRSF13B/TACI and TNFRSF17/BCMA. TNFSF13/APRIL binds to the same 2 receptors. Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B-and T-cell function and the regulation of humoral immunity. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B-cells and the B-cell response.
    • Tissue specificity

      Abundantly expressed in peripheral blood Leukocytes and is specifically expressed in monocytes and macrophages. Also found in the spleen, lymph node, bone marrow, T-cells and dendritic cells. A lower expression seen in placenta, heart, lung, fetal liver, thymus, and pancreas.
    • Sequence similarities

      Belongs to the tumor necrosis factor family.
    • Post-translational

      The soluble form derives from the membrane form by proteolytic processing.
    • Cellular localization

      Secreted and Cell membrane.

      Predicted band size: 31 kDa
      Observed band size: 30,32 kDa
      why is the actual band size different from the predicted?

      Blocking/Dilution buffer: 5% NFDM/TBST.

    • BAFF was immunoprecipitated from 0.35 mg of U937 (human histiocytic lymphoma cell line) whole cell lysate with ab224710 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab224710 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.

      Lane 1: U937 whole cell lysate 10 µg (Input). 

      Lane 2: ab224710 IP in U937 whole cell lysate. 

      Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab224710 in U937 whole cell lysate.

      Blocking and dilution buffer and concentration: 5% NFDM/TBST.

      Exposure time: 20 seconds.

    • Flow cytometric analysis of Daudi (human Burkitt's lymphoma cell line; left panel) and HL-60 (human promyelocytic leukemia cell line ;right panel) cell lines labeling BAFF with ab224710 at 1/500 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) at 1/2000 dilution was used as the secondary antibody.

      Negative control: Daudi. (PMID: 20951740)

      Gated on viable cells.

    • Immunofluorescent analysis of 100% methanol-fixed U937 (human histiocytic lymphoma cell line) cells labeling BAFF with ab224710 at 1/100 dilution followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on U937 cells.

      The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) (red) at 1/200 dilution.

      Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.

      Confocal image showing membranous staining in U-937 cells.

      We don’t recommend PFA fixation, since the result shows some background staining in the nuclear.

      Negative control: HEK-293(PMID: 17393395.
