Recombinant Human TNFRSF18 Protein (Gln26-Glu161), C-hFc and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10079
Official Symbol
TNFRSF18
Product Overview
Biotinylated recombinant human GITR/TNFRSF18 protein (Gln26-Glu161) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Chinese Hamster Ovary 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 Human GITR Ligand/TNFSF18 is immobilized at 0.5 μg/mL (100 μL/well), It binds to Biotinylated Recombinant Human GITR/TNFRSF18 Fc Chimera Avi-tag with an ED50 of 0.05-0.5 μg/mL.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Notes
Disulfide-linked homodimer, biotinylated via Avi-tag
