Human BCMA / TNFRSF17 Protein, Fc Tag (HPLC verified) DMF Filed

分子别名(Synonym)

TNFRSF17,CD269,BCM,BCMA

表达区间及表达系统(Source)

Human BCMA, Fc Tag (HPLC verified) (BC7-H5254) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Ala 54 (Accession # NP_001183.2).

Predicted N-terminus: Met 1

蛋白结构(Molecular Characterization)

Online(Met 1 -  Ala 54) NP_001183.2

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

The protein has a calculated MW of 32.0 kDa. The protein migrates as 34-44 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 0.1 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

>90% as determined by SEC-HPLC.

制剂(Formulation)

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

CAR阳性表达率检测(Evaluation of CAR expression )

FACS Analysis of Anti-BCMA CAR Expression

CAR

293 cells were transfected with anti-BCMA-scFv and RFP tag. 2e5 of the cells were first stained with B. human BCMA / TNFRSF17 protein, Fc tag (Cat. No. BC7-H5254, 3 μg/ml) and C. human Fc tag protein control, followed by FITC-conjugated anti-human IgG Fc antibody. A. Non-transfected 293 cells and C. human Fc 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, Fc tag (Cat. No. BC7-H5254).

背景(Background)

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.
