About recombinant protein
TNFR1 belongs to the TNFR superfamily of transmembrane proteins, and is expressed in most cell types. Binding of either TNF-α or TNF-β to TNFR1 initiates a signal transduction pathway that results in the activation of the transduction factor NFκB, whose target genes are involved in the regulation of inflammatory responses, and, in certain cells induce apoptosis. Soluble TNF Receptor I (sTNFR1) is capable of inhibiting TNF-α and TNF-β activities by acting as a decoy receptor that serves as a sink for the TNF ligands. Recombinant human sTNFR1 is an 18.3 kDa protein (162 amino acid residues) comprising the cysteine rich ligand binding portion of the extracellular domain of the TNFR1 protein.

Activity
Biological activity was determined by its inhibitory effect of the TNF - a mediated cytotoxicity in murine L - 929 cells. The ED50 for this effect in the presence of 0.25 ng/mL of recombinant human TNF - a, is 0.05 μg/mL.

Keep at
The lyophilized Soluble TNF Receptor Type I recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted Soluble TNF Receptor Type I is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing Soluble TNF Receptor Type I recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Description
The receptors are ligand binding factors of type 1, 2 or 3 and protein-molecules that receive chemical-signals from outside a cell. When such chemical-signals couple or bind to a receptor, they cause some form of cellular/tissue-response, e.g. a change in the electrical-activity of a cell. In this sense, am olfactory receptor is a protein-molecule that recognizes and responds to endogenous-chemical signals, chemokinesor cytokines e.g. an acetylcholine-receptor recognizes and responds to its endogenous-ligand, acetylcholine. However, sometimes in pharmacology, the term is also used to include other proteins that are drug-targets, such as enzymes, transporters and ion-channels.

Gene
Tumor necrosis factor (TNFa, tumor necrosis factor alpha, TNFα, cachexin, or cachectin) is a cell signaling protein (cytokine) involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction. It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. TNFb or TNF beta also bin on TNF receptors for Th1 activation.
