Human BCMA/TNFRSF17 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human BCMA/TNFRSF17 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.
It contains Met1-Ala54 [Accession | Q02223-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 8.9 kDa. Due to glycosylation, the protein migrates to 12 kDa and 15-17 kDa based on Bis-Tris PAGE result.

纯度(Purity)

>95% as determined by Bis-Tris PAGE
>95% as determined by HPLC

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

ELISA Data

Immobilized Human BCMA, His Tag at 0.5 μg/ml (100 μl/Well) on the plate. Dose response curve for Anti-BCMA Antibody, hFc Tag with the EC50 of 2.4 ng/ml determined by ELISA.

背景(Background)

B-cell maturation antigen (BCMA or BCM), also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF17), is a protein that in humans is encoded by the TNFRSF17 gene. TNFRSF17 is a cell surface receptor of the TNF receptor superfamily which recognizes B-cell activating factor (BAFF).

分子别名(Synonyms)

CD269; TNFRSF17; BCMA; BCM; TNFRSF13A

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
