Rat TNF-alpha Quantikine ELISA Kit, 2 Plate Summary

Background
The Quantikine Rat TNF-alpha Immunoassay is a 4.5 hour solid phase ELISA designed to measure rat TNF-alpha levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant rat TNF-alpha and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant rat TNF-alpha accurately. Results obtained using nat...ural rat TNF-alpha showed dose response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural rat TNF-alpha.

Background

Tumor necrosis factor alpha (TNF-alpha ), also known as cachectin and TNFSF1A, is the prototypic ligand of the TNF superfamily (1). It is a pleiotropic molecule that plays a central role in inflammation, immune system development, apoptosis, and lipid metabolism (2-5). TNF-alpha is also involved in a number of pathological conditions including asthma, Crohn's disease, rheumatoid arthritis, neuropathic pain, obesity, type 2 diabetes, septic shock, autoimmunity, and cancer (5-11).  
Rat TNF-alpha is synthesized as a 26 kDa type II transmembrane protein that consists of a 35 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 156 aa extracellular domain (ECD) (12). Within the ECD, rat TNF-alpha shares 95% aa sequence identity with mouse, and 73% - 79% aa identity with bovine, canine, cotton rat, equine, feline, human, rhesus macaque, and porcine  TNF-alpha . It 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 (13). Cell surface TNF-alpha can both induce the lysis of tumor cells and virus infected cells, and generate its own downstream cell signaling following ligation by soluble TNF RI (14, 15). Shedding of membrane bound TNF-alpha by TACE/ADAM17 releases the bioactive cytokine, a 55 kDa soluble trimer of the TNF-alpha extracellular domain (16-18).  
TNF-alpha binds the ubiquitous 55 - 60 kDa TNF RI (19, 20) and the hematopoietic cell-restricted 78-80 kDa TNF RII (21, 22), both of which are also expressed as homotrimers (1, 23). Both type I and type II receptors bind TNF-alpha with comparable affinity and can promote NF kappa B activation (24-27). Only TNF RI, however, contains a cytoplasmic death domain which triggers the activation of apoptosis (3, 28). Soluble forms of both types of receptors are released into human serum and urine and can neutralize the biological activity of TNF-alpha (29-31).

FAQs for TNF-alpha (RTA00). (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.
