Name : Human BAFF/TNFSF13B/CD257 Protein
Product Source :
Recombinant Human BAFF/TNFSF13B/CD257 Protein is expressed from HEK293 with hFc tag at the N-Terminus. It contains Ala134-Leu285.[Accession | Q9Y275-1]
Molecular Weight :
The protein has a predicted MW of 41.7 kDa. Due to glycosylation, the protein migrates to 45-48 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 90% as determined by Tris-Bis PAGE> 90% as determined by 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 Human BAFF on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human BAFF is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human BCMA Trimer, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human BAFF, hFc Tag with the EC50 of 5.5ng/ml determined by ELISA (QC Test). SPR Data Human BAFF, hFc Tag captured on CM5 Chip via Protein A can bind Mouse BCMA, His-Avi Tag with an affinity constant of 5.83 μM as determined in SPR assay (Biacore T200).
Background :
B-cell activating factor (BAFF) also known as tumor necrosis factor ligand superfamily member 13B is a protein that in humans is encoded by the TNFSF13B gene.BAFF is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFF-R.
