General description

Mouse monoclonal clone TN3-19.12 anti-Tumor Necrosis Factor-α antibody recognizes mouse and rat TNF-α (approx. 17 kDa in its monomer form and 51 kDa in its homotrimer form) and cross-reacts with mouse TNF-β.

TNF-α is a major mediator of inflammatory responses and its over-production results in extensive tissue damage associated with endotoxemia and cachexia. High serum levels of TNF are associated with septic shock, rejection of renal transplants, parasitic infections, and various neoplastic diseases. TNF-α exhibits growth-enhancing activities for normal cells like fibroblasts, T and B cells, activation of endothelial cells, and differentiation of myeloid cells. In neoplastic cells, TNF-α exerts growth inhibitory activities that can be either cytostatic or cytotoxic.

Physical form

Supplied as a 0.2 μm filtered solution in 0.01 M phosphate buffered saline, pH 7.4.


Mouse monoclonal clone TN3-19.12 anti-Tumor Necrosis Factor-α antibody is a useful tool for the determination and quantification of the TNF-α molecule in many in vitro and in vivo systems. The product may be used in various immunochemical techniques such as immunoblotting, ELISA, immunoprecipitation, and neutralization.
