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

  • Reconstitution
    It is recommended to reconstitute the lyophilized product in sterile deionized water to a final concentration of 1 mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long-term storage.

  • 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.
  • Information by UniProt


  • SDS-page analysis of ab246065 under reducing conditions. The gel was stained overnight with coomassie blue.

    The protein migrates as 50-55 kDa under reducing conditions(SDS-PAGE) due to Glycosylation.


  • Immobilized Human BCMA, Fc Tag, at 5 μg/mL (100 μL/well) can bind ab246065 with a linear range of 1.95-15.6 ng/mL (QC tested).
