    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.

    Receptor for TNFSF13B/BLyS/BAFF and TNFSF13/APRIL. Promotes B-cell survival and plays a role in the regulation of humoral immunity. Activates NF-kappa-B and JNK.
  • Tissue specificity

    Expressed in mature B-cells, but not in T-cells or monocytes.
  • Involvement in disease

    Note=A chromosomal aberration involving TNFRSF17 is found in a form of T-cell acute lymphoblastic leukemia (T-ALL). Translocation t(4;16)(q26;p13) with IL2.
  • Sequence similarities

    Contains 1 TNFR-Cys repeat.
  • Cellular localization

    Cell membrane. Endomembrane system. Perinuclear Golgi-like structures.
  • Information by UniProt


  • 293 cells were transfected with anti-BCMA-scFv and RFP tag. 2e5 of the cells were first stained with B. Biotinylated Human BCMA, Fc,Avitag �and C. biotinylated protein control, followed by FITC-conjugated streptavidin. A. Non-transfected 293 cells and C. biotinylated protein control were used as negative control. RFP was used to evaluate CAR (anti-BCMA-scFv) expression and FITC was used to evaluate the binding activity of Biotinylated Human BCMA, Fc,Avitag .
  • SDS-PAGE - Human BCMA protein (Fc Chimera Active) (Biotin) (ab246079).

    The gel was stained overnight with Coomassie Blue.

    As a result of glycosylation, the protein migrates as 40-45 kDa under reducing conditions (shown in image), and 70-85 kDa under non-reducing conditions (not shown).

  • Immobilized Human BAFF, Fc Tag at 5 μg/mL (100 μL/well) can bind ab246079 with a linear range of 0.12-1.95 ng/mL.

  • Immobilized Anti-Human BCMA Mab at 2 μg/mL (100 μL/well) can bind ab246079 with a linear range of 0.1-3 ng/mL.
