Human GITR, His Tag (GIR-H5228) is expressed from human 293 cells (HEK293). It contains AA Gln 26 - Glu 161 (Accession # Q9Y5U5-1).
Predicted N-terminus: Gln 26
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 16.4 kDa. The protein migrates as 20-25 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>92% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

The purity of Human GITR, His Tag (Cat. No. GIR-H5228) was more than 90% and the molecular weight of this protein is around 18-25 kDa verified by SEC-MALS.
Immobilized Human GITR Ligand, Fc Tag (Cat. No. GIL-H526a) at 10 μg/mL (100 μL/well) can bind Human GITR, His Tag (Cat. No. GIR-H5228) with a linear range of 0.01-0.313 μg/mL (QC tested).
Glucocorticoid-induced TNFR-related protein (GITR) is also known as Tumor necrosis factor receptor superfamily member 18 (TNFRSF18), activation-inducible TNFR family receptor (AITR), CD antigen CD357, which is a member of the tumor necrosis factor receptor (TNF-R) superfamily. GITR is receptor for TNFSF18, which seems to be involved in interactions between activated T-lymphocytes and endothelial cells and in the regulation of T-cell receptor-mediated cell death. GITR also mediated NF-kappa-B activation via the TRAF2/NIK pathway.
