  • Tested applications
    Suitable for: Flow Cyt, ELISA, Indirect ELISA, Neutralising, WBmore details
  • Species reactivity
    Reacts with: Human
  • Immunogen

    Recombinant full length protein (Human).

  • Positive control
  • General notes

    This antibody can be used in two-site immunoassay for the determination of human TNF alpha. It recognizes a different epitope than the monoclonal antibody ab9813. The two-site immunoassay can be used to determine TNF alpha concentration in the cultures of human peripheral blood mononuclear cells. Can also be used to neutralize TNF alpha cytotoxic activity in vitro. At a concentration of 2.5 µg/ml, antibody ab9809 causes 50% inhibition of TNF alpha mediated cytotoxicity on L929 cells.

    This product was changed from ascites to tissue culture supernatant on 28/11/2017. Lot numbers higher than GR151594-8 will be from tissue culture supernatant. Please note that the dilutions may need to be adjusted accordingly.

Target

  • Function
    Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.
  • Involvement in disease
    Genetic variations in TNF are a cause of susceptibility psoriatic arthritis (PSORAS) [MIM:607507]. PSORAS is an inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoidlike pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis).
  • Sequence similarities
    Belongs to the tumor necrosis factor family.
  • Post-translational
    modifications
    The soluble form derives from the membrane form by proteolytic processing.
    The membrane form, but not the soluble form, is phosphorylated on serine residues. Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1.
    O-glycosylated; glycans contain galactose, N-acetylgalactosamine and N-acetylneuraminic acid.

Images

  • Overlay histogram showing THP1 cells stained with ab9809 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab9809, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
