Name : Human BAFFR/TNFRSF13C Protein
Product Source :
Recombinant Human BAFFR/TNFRSF13C Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ser7-Ala71.[Accession | Q96RJ3-1]
Molecular Weight :
The protein has a predicted MW of 7.6 kDa. Due to glycosylation, the protein migrates to 13-25 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
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 Human BAFFR on Tris-Bis PAGE under reduced conditions. The purity is greater than 95%. ELISA Data Immobilized Human BAFFR, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human BAFF (Trimer) , His Tag with the EC50 of 69.9ng/ml determined by ELISA (QC Test). ELISA Data Immobilized Human BAFFR, His Tag at 0.5μg/ml (100μl/Well). Dose response curve for Anti-BAFFR Antibody, hFc Tag with the EC50 of 6.2ng/ml determined by ELISA. SPR Data Human BAFFR, His Tag captured on CM5 Chip via anti-his antibody can bind Human BAFF Trimer, hFc-Flag Tag with an affinity constant of 1.21 nM as determined in SPR assay (Biacore T200).
Background :
BAFF binds to three TNF receptor superfamily members: B-cell maturation antigen (BCMA/TNFRSF17), transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI/TNFRSF13B) and BAFF Receptor (BAFF R/BR3/TNFRSF13C). These receptors are type III transmembrane proteins that lack a signal peptide. Whereas TACI and BCMA bind BAFF and another TNF superfamily ligand, APRIL (a proliferation-inducing ligand), BAFF R selectively binds BAFF.
Synonyms :
CD268; BAFFR; BR3; TNFRSF13C; BROMIX; CVID4; prolixin
