General description

Monoclonal Anti-Mouse Tumor Necrosis Factor-α (TNF-α) is derived from the TN3-19.12 hybridoma produced by the fusion of mouse myeloma cells (P3X63-Ag8.653) and splenocytes from male Armenian hamster immunized with purified mouse recombinant TNF-α. Tumor necrosis factor (TNF) protein family contains two members: TNF-α (also known as cachectin) and TNF-β (also known as lymphotoxin). These proteins are small molecules with a molecular weight of 17 and 25 kDa respectively and share 30% amino acid homology. TNF-α and -β are secreted from many different cells such as lymphocytes, neutrophils, and macrophages.

Specificity

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.

Immunogen

purified recombinant mouse TNF-α.

Application

Monoclonal Anti-Tumor Necrosis Factor-α antibody produced in hamster has been used in:
  • immunoblotting
  • enzyme-linked immunosorbent assay (ELISA)
  • immunoprecipitation
  • neutralization

Biochem/physiol Actions

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.
