分子别名(Synonym)

TNFRSF17,CD269,BCM,BCMA

表达区间及表达系统(Source)

Biotinylated Human BCMA, His,Avitag™ (BCA-H82E4) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Ala 54 (Accession # Q02223-1).

Predicted N-terminus: Met 1

蛋白结构(Molecular Characterization)

Online(Met 1 - Ala 54) Q02223-1

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.

The protein has a calculated MW of 9.6 kDa. The protein migrates as 12 kDa and 15-17 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Biotin:Protein Ratio)

The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

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

Protocol

 

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. Biotinylated Human BCMA, His,Avitag (Cat. No. BCA-H82E4, 1 μg/mL) and C. Biotinylated Protein Control, followed by FITC 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, His,Avitag (Cat. No. BCA-H82E4).

Protocol

 

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.
