Overview
Product name Active Recombinant Human TNF-alpha Protein Catalog No. RP00001 Description Active Recombinant Human TNF-alpha Protein is produced by E. coli expression system. The target protein is expressed with sequence (Val77-Leu233) of human TNF-alpha (Accession #NP_000585.2) fused with an initial Met at the N-terminus and a 6×His tag at the C-terminus. Bio-Activity Measured in a cytotoxicity assay using L-929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 25-100 pg/mL. Purity > 97% by SDS-PAGE. Endotoxin < 0.1 EU/μg of the protein by LAL method. Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. Species Human Background
Tumor necrosis factor alpha (TNF-alpha), also known as TNF, TNFA or TNFSF2, is the prototypic cytokine of the TNF superfamily. This cytokine is mainly secreted by macrophages. It can bind to, and thus functions through its receptors TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. This cytokine is involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. This cytokine has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer. KNockout studies in mice also suggested the neuroprotective function of this cytokine.Product information
