Name : Human TNFSF15 Trimer Protein
Product Source :
Recombinant Human TNFSF15 Trimer Protein is expressed from HEK293 with His tag and Flag tag at the N-Terminus. It contains Asp91-Leu251.[Accession | O95150-1]
Molecular Weight :
The protein has a predicted MW of 58.2 kDa. Due to glycosylation, the protein migrates to 65-75 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 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 TNFSF15 Trimer on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human TNFSF15 Trimer is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human TNFSF15 Trimer, His Tag at 1μg/ml (100μl/Well) on the plate. Dose response curve for Anti-TNFSF15 Antibody, hFc Tag with the EC50 of 3.4ng/ml determined by ELISA (QC Test). SPR Data Mouse DR3, His Tag immobilized on CM5 Chip can bind Human TNFSF15 (Trimer) , His Tag with an affinity constant of 3.06 nM as determined in SPR assay (Biacore T200).
Background :
TNF superfamily member 15 (TNFSF15), a cytokine largely produced by vascular endothelial cells and a specific inhibitor of the proliferation of these same cells, can inhibit VEGF-induced vascular permeability in vitro and in vivo, and that death receptor 3 (DR3), a cell surface receptor of TNFSF15, mediates TNFSF15-induced dephosphorylation of VEGFR2.
Synonyms :
TL1A; VEGI-251; TNFSF15; TL1; VEGI; VEGI192A
