Recombinant Human TNF alpha (Catalog NO. HZ-1014) inihibits the growth of L-929 cell line in a dose dependent manner (blue curve). The activity elicited by recombinant Human TNF alpha (5 ng/mL HZ-1014) is neutralized (red curve) by Mouse anti-human TNF alpha monoclonal antibody (Catalog NO. 69002-1-Ig). The ND50 is typically 10-50ng/mL.
TNF, as also known as TNF-alpha, or cachectin, is a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. It is expressed as a 26 kDa membrane bound protein and is then cleaved by TNF-alpha converting enzyme (TACE) to release the soluble 17 kDa monomer, which forms homotrimers in circulation. 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. 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.
This antibody is used to Block/Neutralize TNF alpha protein.
