Human BCMA / TNFRSF17 Protein,His Tag

  • Synonym
  • Source
    Human BCMA, His Tag (BCA-H522y) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Ala 54 (Accession # Q02223-1).
    Predicted N-terminus: Met 1
  • Molecular Characterization
    BCMA(Met 1 - Ala 54) Q02223-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 7.8 kDa. The protein migrates as 12 kDa and 15-17 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss was observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.

Anti-Human BCMA MAb (human IgG1) captured on CM5 chip via Anti-Human IgG Fc antibodies surface, can bind Human BCMA, His Tag (Cat. No. BCA-H522y) with an affinity constant of 32.3 nM as determined in a SPR assay (Biacore T200) (Routinely tested).

Evaluation of CAR expression
FACS Analysis of Anti-BCMA CAR Expression
Evaluation of CAR expression

293 cells were transfected with anti-BCMA-scFv and RFP tag. 2e5 of the cells were first stained with B. human BCMA / TNFRSF17 protein, His tag (Cat. No. BCA-H522y, 0.03 μg/ml) and C. His tag protein control, followed by FITC-conjugated anti-6xHis tag antibody. A. Non-transfected 293 cells and C. His tag 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 human BCMA / TNFRSF17 protein, His tag (Cat. No. BCA-H522y).
