背景介绍

TNFR-1 is a member of the TNF receptor superfamily of proteins which is found in membrane-bound and soluble forms that interact with membrane-bound and soluble forms, respectively, of its ligand, tumor necrosis factor alpha. Binding of membrane-bound tumor necrosis factor alpha to the membrane-bound receptor induces receptor trimerization and activation, which plays a role in cell survival, apoptosis, and inflammation. Proteolytic processing of the encoded receptor results in release of the soluble form of the receptor, which can interact with free tumor necrosis factor alpha to inhibit inflammation. Mice lacking a functional copy of this gene exhibit impaired immune function.

生物活性
- Measured by its ability to inhibit the TNF-α mediated cytotoxicity in the L‑929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D.The EC50 for this effect is less than 1.5ng/mL in the presence of 0.25 ng/mL Recombinant Human TNF‑ α.
电泳(SDS-PAGE)
- 2μg (R: reducing conditions, N: non-reducing conditions).
反相高效液相色谱(RP-HPLC)
