FITC-Labeled Human BCMA, Fc Tag (BCA-HF254) is expressed from human HEK293 cells. It contains AA Met 1 - Ala 54 (Accession # Q02223). It is the FITC labeled form of Human BCMA, Fc Tag (Cat. No. BC7-H5254).

Predicted N-terminus: Met 1

Molecular Characterization

BCMA(Met 1 - Ala 54)NP_001183.2
Fc(Glu 99 - Lys 330)P01857

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 32 kDa. As a result of glycosylation, the protein migrates as 38-42 kDa under reducing (R) condition, and 60-70 kDa under non-reducing (NR) condition (SDS-PAGE).



Excitation source: 488 nm spectral line, argon-ion laser

Excitation Wavelength: 494 nm

Emission Wavelength: 518 nm


The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular seive treatment during purification process.

FITC:Protein Ratio

The FITC to protein molar ratio is 2-3 as determined by BCA or UV-Vis absorbance.


Less than 1.0 EU per μg by the LAL method.


>92% as determined by SDS-PAGE.


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

Request for protocol



Tumor necrosis factor receptor superfamily member 17 (TNFRSF17) is also known as B-cell maturation protein (BCMA), CD antigen CD269, which is a member of the TNF-receptor superfamily. TNFRSF17 contains one TNFR-Cys repeat. TNFRSF17 is expressed in mature B-cells, but not in T-cells or monocytes. TNFRSF17 is receptor for TNFSF13B/BLyS/BAFF and TNFSF13/APRIL. TNFRSF17 promotes B-cell survival and plays a role in the regulation of humoral immunity. TNFRSF17 can activate NF-kappa-B and JNK.
