TNF-alpha Antibody [Unconjugated] Summary

E. coli-derived recombinant rat TNF-alpha
Accession # P16599
Detects rat TNF‑ alpha in direct ELISAs and Western blots. In Western blots, approximately 25% cross-reactivity with recombinant porcine TNF-alpha is observed and less than 1% cross-reactivity with recombinant human (rh) TNF-beta, rhTNF sRI, and rhTNF sRII is observed. In direct ELISAs, approximately 40% cross-reactivity with recombinant canine TNF-alpha, recombinant feline TNF-alpha, and recombinant rhesus macaque TNF-alpha is observed. Neutralizes the biological activity of rat TNF-alpha. This antibody will also neutralize the biological activity of murine TNF-alpha, but weak neutralization of rhTNF-alpha and no neutralization of rhTNF-beta was observed.

Tumor Necrosis Factor Alpha (TNF-alpha ) 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, apoptosis, and immune system development. TNF-alpha is produced by a wide variety of immune and epithelial cell types (1, 2). Rat TNF-alpha consisits of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 179 aa extracellular domain (ECD) (3). Within the ECD, rat TNF-alpha shares 94% aa sequence identity with mouse and 69% - 76% with bovine, canine, cotton rat, equine, feline, human, porcine, and rhesus TNF-alpha. The 26 kDa type 2 transmembrane protein is assembled intracellularly to form a noncovalently linked homotrimer (4). Ligation of this complex induces reverse signaling that promotes lymphocyte co-stimulation but diminishes monocyte responsiveness (5). Cleavage of membrane bound TNF-alpha by TACE/ADAM17 releases a 55 kDa soluble trimeric form of TNF-alpha (6, 7). TNF-alpha trimers bind the ubiquitous TNF RI and the hematopoietic cell-restricted TNF RII, both of which are also expressed as homotrimers (1, 8). TNF-alpha regulates lymphoid tissue development through control of apoptosis (2). It also promotes inflammatory responses by inducing the activation of vascular endothelial cells and macrophages (2). TNF-alpha is a key cytokine in the development of several inflammatory disorders (9). It contributes to the development of type 2 diabetes through its effects on insulin resistance and fatty acid metabolism (10, 11).

FAQs for TNF-alpha Antibody (AF-510-NA). (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.
