Application Notes
The biotinylated rabbit anti-mouse/rat TNF-alpha polyclonal antibody has been tested as the detection antibody in a sandwich ELISA for analysis of mouse or rat TNF-alpha in combination with the purified anti-mouse/rat TNF-alpha monoclonal antibody, clone TN3.19 (NBP1-43235) for capture and recombinant mouse TNF-alpha (NBP1-43197) or rat TNF-alpha (NBP1-43197) as the standard. A suitable range of concentrations of this biotinylated antibody for ELISA detection is 0.5 - 2.0 ug/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 2000 pg/ml - 15 pg/ml (mouse TNF-alpha) or 5000 - 30 pg/ml (rat TNF-alpha) should be included in each ELISA plate. Recognition of mouse TNF-alpha by this assay is not interfered with by 1000x excess soluble TNF-alpha receptor type I or II.

Reactivity Notes

Mouse, Rat


The affinity purified polyclonal rabbit antibody reacts with mouse and rat tumor necrosis factor-alpha. Mouse TNF alpha is a 17 kDa factor produced by macrophages, monocytes, neutrophils, CD4 T cells, and NK cells. A 26 kDa form is expressed as a membranebound molecule. TNF alpha is cytolytic and plays an important role in immune regulation. Bioactive TNF alpha exists as a homotrimer.

FAQs for TNF-alpha Antibody (NBP2-00399). (Showing 1 - 4 of 4 FAQ).

  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.
