Background

Tumor necrosis factor alpha (TNF-alpha, TNF- alpha , TNFA ), also known as Cachectin and TNFSF2, is the prototypic ligand of the TNF superfamily. It is a pleiotropic molecule that plays a central role in inflammation, immune system development, apoptosis, and lipid metabolism. TNF-alpha is produced by several lymphoid cells as well as by astrocytes, endothelial cells, and smooth muscle cells. Mouse TNF-alpha consists of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 179 aa extracellular domain (ECD). Within the ECD, mouse TNF-alpha shares 94% aa sequence identity with rat and 70%-77% with bovine, canine, cotton rat, equine, feline, human, porcine, and rhesus TNF-alpha. TNF-alpha is produced by a wide variety of immune, epithelial, endothelial, and tumor cells. TNF-alpha is assembled intracellularly to form a noncovalently linked homotrimer which is expressed on the cell surface. Cell surface TNF-alpha can induce the lysis of neighboring tumor cells and virus infected cells, and it can generate its own downstream cell signaling following ligation by soluble TNFR I. Shedding of membrane bound TNF-alpha by TACE/ADAM17 releases the bioactive cytokine, a 55 kDa molecular weight soluble trimer of the TNF-alpha extracellular domain. TNF-alpha binds the ubiquitous 55-60 kDa TNF RI and the hematopoietic cell-restricted 80 kDa TNF RII, both of which are also expressed as homotrimers present on virtually all cell types. Both type I and type II receptors bind TNF-alpha with comparable affinity, although only TNF RI contains a cytoplasmic death domain which triggers the activation of apoptosis. Soluble forms of both types of receptors are released and can neutralize the biological activity of TNF-alpha.

FAQs for TNF-alpha Antibody (MAB410). (Showing 1 - 4 of 4 FAQs).

1. I need to know about TNF-alpha antibody kits for mice.
   • We currently have two TNFalpha ELISA kits specific for mouse: catalog numbers KA0257 and NBP1-92670.
2. I would like to ask you for help. I need an antibody for Elisa to detect human TNF alpha in a supernatant from a cell culture (meaning supernatant after centrifugation of collected cell suspension from a plate well). Which of your antibodies against human tnf alpha would be suitable? I would like to buy only the primary antibody.
   • I would recommend catalog number NBP1-67821 or NB600-587; however, a full list of our anti-human TNF alpha antibodies suitable for use in ELISA can be found using this link.
3. I am interested in a TNF alpha antibody, cross reactive for human, rat and mouse (host species: rabbit). Could your product NBP1-19532 be used in western blotting applications? Or do you have a similar product in your catalog which could fit with my request?
   • The antibody you mention, NBP1-19532, has not yet been validated in Western blot. I would instead recommend either NBP1-67821 or NB600-587. These are both rabbit polyclonal antibodies that cross-reacts with human, mouse and rat and have been used in Western blotting.
4. Can your TNF-alpha products be used to treat TBI victims and therefore avoid the perispinal injections with Enbrel?
   • I am very sorry, but all of our products are for scientific research use only, and none are intended or approved for use in humans.
