Name : Biotinylated Human BCMA/TNFRSF17 Trimer Protein

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

Molecular Weight :
The protein has a predicted MW of 29.5 kDa. Due to glycosylation, the protein migrates to 35-50 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by SEC-HPLC

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

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

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Biotunylated Human BCMA Trimer on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Biotunylated Human BCMA Trimer is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human BAFF, hFc Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human BCMA Trimer, His Tag with the EC50 of 11.1ng/ml determined by ELISA (QC Test). ELISA Data Immobilized Anti-BCMA Antibody at 1μg/ml (100μl/well) on the plate. Dose response curve for Biotunylated Human BCMA Trimer, His Tag with the EC50 of 1.9ng/ml determined by ELISA.

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).

Synonyms :
CD269; TNFRSF17; BCMA; BCM; TNFRSF13A
