Applications
The Abpromise guarantee
Our Abpromise guarantee covers the use of ab9739 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| WB | (8) |
Use at an assay dependent concentration.
To detect TNF alpha by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant TNF alpha is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions. The presursor is ~26 kDa and the secreted form is ~17 kDa. |
| Sandwich ELISA |
Use at an assay dependent concentration.
To detect Murine TNF alpha by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of ab9739 is required. This antigen affinity purified antibody, in conjunction with ab245857 detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Murine TNF alpha. |

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
modificationsThe 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. -
