Biotinylated Human GITR/TNFRSF18 Protein (GTR-HM401B)
|Recombinant Biotinylated Human GITR/TNFRSF18 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Gln26-Glu161.
|GITR (glucocorticoid-induced tumor necrosis factor receptor), also known as AITR and TNFRSF18, is a 40 kDa transmembrane glycoprotein that functions in immune regulation.GIRT is a receptor for TNFSF18. Seems to be involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. Mediated NF-kappa-B activation via the TRAF2/NIK pathway.

|The protein has a predicted MW of 17.2 kDa. Due to glycosylation, the protein migrates to 26-28 kDa based on Tris-Bis PAGE result.
|Immobilized Human GITR Ligand Trimer, hFc Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Biotinylated Human GITR, His Tag with the EC50 of 77.9ng/ml determined by ELISA. See testing image for detail.
|> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
|Less than 1EU per ug by the LAL method.
|Shipped at ambient temperature.
|Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
|Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
|Stability And Storage
|Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
