Recombinant Human TNFRSF18, Fc Chimera

Cat. No.: TNFRSF18-1621H
Product Overview: Recombinant Human TNFRSF18 encoding the signal peptide from hCD33 (Met 1 - Ala 16) joined with the extracellular domain of human GITR (amino acid residues 26 - 161) was fused to the Fc region of human IgG1 via a polypeptide linker and expressed inNSO cells.
Description: GITR (glucocorticoid-induced tumor necrosis factor receptor) also known as TNFRSF18, is a surface receptor molecule that has been shown to be involved in inhibiting the suppressive activity of T-regulatory cells and extending the survival of T-effector cells.1 GITR is involved in the regulation of T-cell receptor mediated cell death. Constitutive expression of a transfected GITR gene induces resistance to apoptosis induced by anti CD3 monoclonal antibodies. GITR ligand interferes with the suppressor activity of CD4(+) CD25(+) regulatory T-cells.
Source: NSO Cells.
State Of Matter: Lyophilized.
Purity: >90% by SDS Page and analyzed by silver stain.
Endotoxin: <1.0 EU/µg as determined by the LAL method.
Molecular Weight: The predicted molecular weight of Recombinant Human GITR is Mr 41 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 50 kDa.
Formulation: This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Biological Activity: Measured by its ability to bind GITR ligand. Immobilized Human GITR at 2 μg/ml (100 μl/well) can bind Human GITR ligand with a linear range of 0.3 - 20 ng/ml in a functional ELISA assay.
Storage And Stability: This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
