TNF-alpha Antibody (Hu7) [Unconjugated]

Human peripheral blood mononuclear cells (PBMCs) (A) treated with PMA and Ca2+ ionomycin overnight, or (B) resting, were stained with Human Anti-Human TNF- alpha (Research Grade Adalimumab Biosimilar) Monoclonal Antibody (Catalog # MAB9677) followed by Goat anti-Human APC-conjugated Secondary Antibody (Catalog # F0135) and Mouse anti-Human CD3 PE-conjugated Monoclonal Antibody (Catalog # FAB100P). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Recombinant Human TNF-alpha (Catalog # 210-TA) induces cytotoxicity in the the L-929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Cytotoxicity elicited by Recombinant Human TNF-alpha (0.25 ng/mL) is neutralized (green line) by increasing concentrations of Human Anti-Human TNF-alpha (Research Grade Adalimumab Biosimilar) Monoclonal Antibody (Catalog # MAB9677). The ND50 is typically 2-12 ng/mL in the presence of the metabolic inhibitor actinomycin D.

Biosimilar antibody development at Bio-Techne includes in silico design and engineering to generate both light chain (lc) and heavy chain (hc) sequences for each antibody. After transfection of the dual expression vector, Bio-Techne’s biosimilar antibodies undergo rigorous application testing to ensure the final biosimilar product is suited for your research needs.

Background

Adalimumab is a biosimilar directed against the extracellular domain of TNF- alpha . This constitutes the immunogen used for the anti-Idiotype catalog numbers MAB9616 and MAB9546. The biotinylated antibody (catalog number IC9677B) can be used in flow cytometry or various assay format to measure EGFR expression and can be detected by conjugated streptavidin.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.

FAQs for TNF-alpha Antibody (MAB9677). (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.
