Description

General description

Tumor necrosis factor- α(TNF-α), also known as cachectin, is an inflammatory cytokine that exists primarily as a 51kDa complex built up of 3 identical, non-covalently-linked polypeptide subunits (17 kDa, 157 amino acid residues, in human). TNF- αoccurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. TNF-α is secreted by neutrophils, activated lymphocytes, macrophages, NK cells, LAK cells, astrocytes, endothelial cells, smooth muscle cells, and some transformed cells.

Specificity

The antibody binds to TNF-α. It does not cross-react with recombinant human TNF-β, IL-1a, IL-1β or IL-3, nor with recombinant mouse or human IL-6.

Immunogen

recombinant human TNF-α produced in bacteria.

Application

Anti-Tumor Necrosis Factor-α antibody may be used for dot blot at a working antibody dilution of 1:2000. The antibody may be used for neutralization assay; the ND50 is 1-3 μg/ml. Anti-TNF-α antibody was used for neutralization of TNF-α of Jurkat cells.

Anti-Tumor Necrosis Factor-α antibody produced in rabbit has been used in western blotting. It may also be used in enzyme linked immunoassay (ELISA).

Biochem/physiol Actions

Tumor Necrosis Factor-α (TNF-α) is a cytokine produced by macrophages in response to stimulus by LPS. It plays a major role in mediating inflammation, tissue injury, pathogenic shock, innate immunity, apoptosis and autoimmunity. The physiological effects of TNF-α are mediated by receptors of TNFR super family. The TNF/TNFR signaling axis plays a critical role in mediating either survival or apoptosis depending on the class of adaptor proteins recruited in the cell. Association of receptors with a death domain causes rapid activation of caspases and results in cell death. TNF/TNFR also results in the activation of downstream pathways involving MAPK, p38, JNK and NF-κB that play a major role in innate immunity, acute inflammatory responses and homeostasis. The TNF/TNFR axis is also important in the pathology of various autoimmune and inflammatory disorders including a variety of malignancies and Alzheimer′s disease.
