| Product Specific Information |
| For dilution, use a buffer containing carrier protein, e.g. PBS with 1% BSA or a neutral media containing 10% FCS and freeze in aliquots at -70°C. Activity: The biological activity of recombinant bovine TNFa was measured by its cytolytic effect on mouse WEHI-13VAR cells in the presence of Actinomycin D. The ED50 (or 1 unit of activity) for this effect in our laboratories typically falls into the range of 28.4 – 42.7 ng/ml. Expression: The mature, soluble form of bovine TNF-alpha was expressed in Pichia pastoris, KM71H. GenBank® Accession # Q06599, amino acids 77 - 233. For protein verification, the expressed protein was N-terminal sequenced and begins with the following 10 amino acids: LRSSSQASSN. |
| General Information |
| This gene encodes a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (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. |
