The TN3-19.12 monoclonal antibody reacts with mouse, rat, and rabbit TNF╬▒ (tumor necrosis factor-alpha) a multifunctional proinflammatory cytokine. TNF╬▒ exists as a soluble 17 kDa monomer, which forms homotrimers in circulation or as a 26 kDa membrane-bound form. TNF╬▒ belongs to the TNF superfamily of cytokines and signals through its two receptors, TNFR1 and TNFR2 which can be activated by both the soluble trimeric and membrane-bound and forms of TNF╬▒. TNF╬▒ is primarily produced by macrophages in response to foreign antigens such as bacteria (lipopolysaccharides), viruses, and parasites as well as mitogens and other cytokines but can also be expressed by monocytes, neutrophils, NK cells, CD4 T cells and some specialized dendritic cells. TNF╬▒ is known to play key roles in a wide spectrum of biological processes including immunoregulation, cell proliferation, differentiation, apoptosis, antitumor activity, inflammation, anorexia, cachexia, septic shock, hematopoiesis, and viral replication. TNF╬▒ dysregulation has been implicated in a variety of diseases, including autoimmune diseases, insulin resistance, and cancer. Mouse and human TNF╬▒ share 79% amino acid sequence identity however, mouse TNF╬▒ is glycosylated while human TNF╬▒ is not. TNF╬▒ knockout animals display defects in response to bacterial infection, characterized by defects in forming organized follicular dendritic cell networks and germinal centers with a lack of primary B cell follicles. The TN3-19.12 antibody can neutralize the bioactivity of natural or recombinant TNF-╬▒.
