Recombinant Monkey TNFRSF1B Protein (Leu23-Asp257), C-Fc-tagged
Product Description
Cat
IMP-9585
Official Symbol
TNFRSF1B
Product Overview
Recombinant Cynomolgus TNF RII/TNFRSF1B protein (Leu23-Asp257) with a human IgG1 (Pro100-Lys330) Fc tag at C-terminus was expressed in Chinese Hamster Ovary cell line.
Description
The protein encoded by this gene is a member of the TNF-receptor superfamily. This protein and TNF-receptor 1 form a heterocomplex that mediates the recruitment of two anti-apoptotic proteins, c-IAP1 and c-IAP2, which possess E3 ubiquitin ligase activity. The function of IAPs in TNF-receptor signalling is unknown, however, c-IAP1 is thought to potentiate TNF-induced apoptosis by the ubiquitination and degradation of TNF-receptor-associated factor 2, which mediates anti-apoptotic signals. Knockout studies in mice also suggest a role of this protein in protecting neurons from apoptosis by stimulating antioxidative pathways.

Bio-activity
Measured by its ability to inhibit the TNF-alpha mediated cytotoxicity in the L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is 0.2-1.2 ng/mL in the presence of 0.25 ng/mL of Recombinant Human TNF-alpha.
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
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
