Recombinant Human TNF-alpha Protein Summary
A Partial Recombinant Proteins to TNF-alpha.
E. coli expressed amino acids Val 77-Leu 233 of human TNF-a (accession # HUMTNFAB).
|Details of Functionality
Measured by mouse L929 cytotoxicity assay. The ED50 measured in a L929 killing assay is typically 0.01 ng/ml, corresponding to a specific activity of approximately 1.0 x10^8 Units/mg.
| Protein/Peptide Type
Partial Recombinant Protein
Less than 0.01 ng/ug cytokine as determined by the LAL assay.
This recombinant human TNF-α has been tested by sandwich ELISA using anti-human TNF-α antibody pair (MAb1/MAb11) and in bioassay using mouse cell line L929.
This protein was made to the human sequence.

Human TNF-alpha is a 17 kDa factor produced by macrophages, monocytes, neutrophils, CD4+ T cells and NK cells. A 26 kDa form of TNF-alpha is expressed as a membrane bound molecule. TNF-alpha is cytolytic and plays an important role in immune regulation. Dimers and trimers of TNF-alpha have been observed.

FAQs for TNF-alpha Protein (NBP1-43196). (Showing 1 - 4 of 4 FAQ).
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.
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.
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.
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.
