Name : Human OX40 Ligand/TNFSF4 Trimer Protein
Product Source :
Recombinant Human OX40 Ligand/TNFSF4 Trimer Protein is expressed from HEK293 with His tag and Flag tag at the N-Terminus. It contains Gln51-Leu183.[Accession | P23510-1]
Molecular Weight :
The protein has a predicted MW of 49.7 kDa. Due to glycosylation, the protein migrates to 65-140 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
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 OX40 Ligand Trimer on Tris-Bis PAGE under reduced condition. The purity is greater than 90%. ELISA Data Immobilized Human OX40 Ligand Trimer, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human OX40, hFc Tag with the EC50 of 37.7ng/ml determined by ELISA.
Background :
Tumor necrosis factor ligand superfamily member 4 (TNFSF4) is also known as glycoprotein Gp34, OX40 ligand (OX40L),which belongs to the tumor necrosis factor family. It is expressed on such cells as DC2s (a subtype of dendritic cells) enabling amplification of Th2 cell differentiation.
Synonyms :
OX40L; OX-40L; OX4OL; CD252; TNFSF4; OX40 Ligand; CD134 ligand; CD134L; TXGP1; Glycoprotein Gp34
