Human BCMA / TNFRSF17 Protein, Fc Tag, premium grade 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, premium grade (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

It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

蛋白结构(Molecular Characterization)

BCMA Structure

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 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 0.01 EU per μg by the LAL method.

无菌(Sterility)

The sterility testing was performed by membrane filtration method.

支原体(Mycoplasma)

Negative.

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 with trehalose as protectant.

活性(Bioactivity)-ELISA

BCMA ELISA

Immobilized Biotinylated Human BAFF, His,Avitag (Cat. No. BAF-H82Q2) at 1 μg/mL (100 μL/well) on streptavidin precoated (0.2 μg/well) plate, can bind Human BCMA, Fc Tag, premium grade (Cat. No. BC7-H5254) with a linear range of 0.1-0.8 ng/mL (QC tested).

Protocol

BCMA ELISA

Immobilized Human BCMA, Fc Tag, premium grade (Cat. No. BC7-H5254) at 2 μg/mL (100 μL/well) can bind Anti-Human BCMA Mab with a linear range of 0.1-1.6 ng/mL (Routinely tested).

Protocol

BCMA ELISA

Immobilized Human APRIL, His,Flag Tag, active trimer (Cat. No. APL-H52D1) at 1 μg/mL (100 μL/well) can bind Human BCMA, Fc Tag, premium grade (Cat. No. BC7-H5254) with a linear range of 0.1-2 ng/mL (Routinely tested).

Protocol

 

活性(Bioactivity)-BLI

BCMA BLI

Loaded Human APRIL, His,Flag Tag, active trimer (Cat. No. APL-H52D1) on HIS1K Biosensor, can bind Human BCMA, Fc Tag, premium grade (Cat. No. BC7-H5254) with an affinity constant of 1.88 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

Protocol

 

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

FACS Analysis of Anti-BCMA CAR Expression

BCMA CAR_T

293 cells were transfected with anti-BCMA-scFv and RFP tag. 2e5 of the cells were first stained with B. Human BCMA, Fc Tag, premium grade (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, Fc Tag, premium grade (Cat. No. BC7-H5254).

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.
