Recombinant Rat TNFRSF18 Protein (Glu25-His153), C-mFc-tagged
Product Description
Cat
IMP-9944
Official Symbol
Tnfrsf18
Product Overview
Recombinant Rat GITR/TNFRSF18 protein (Glu25-His153) with a Mouse IgG2a (Glu98-Lys330) Fc tag at C-terminus was expressed in Mouse myeloma cell line.
Description
This gene encodes a member of the TNF-receptor superfamily. The encoded receptor has been shown to have increased expression upon T-cell activation, and it is thought to play a key role in dominant immunological self-tolerance maintained by CD25(+)CD4(+) regulatory T cells. Knockout studies in mice also suggest the role of this receptor is in the regulation of CD3-driven T-cell activation and programmed cell death. Three alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.

Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Rat GITR/TNFRSF18 Fc Chimera is immobilized at 2 μg/mL, 100 μL/well, the concentration of Recombinant Mouse GITR Ligand/TNFSF18 aa 47-173 that produces 50% of the optimal binding response is 25-150 ng/mL
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>90%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Notes
Disulfide-linked homodimer
