Recombinant fragment corresponding to Mouse TNF alpha aa 80-235. E.coli-derived recombinant MurineTNF-alpha
Database link: P06804
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.
|IHC-Fr||Use at an assay dependent concentration. PubMed: 18458097|
|IHC-P||Use at an assay dependent concentration.|
|WB||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.
|Neutralising||Use at an assay dependent concentration. To yield one-half maximal inhibition [ND50] of the biological activity of mTNF-alpha (0.25 ng/ml), a concentration of 0.08 – 0.10 µg/ml of this antibody is required.|
|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 a suitable detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Murine TNF alpha.
|ICC/IF||Use a concentration of 5 µg/ml.|
ICC/IF image of ab9739 stained A431 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab9739 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
Immunohistochemical analysis of colchicine injected mouse brain (hippocampus CA1 region) tissue using ab9739 at 1.0 μg/ml overnight at 4˚C. This was followed by a peroxidase conjugated secondary antibody and then a fluorescein Tyramide Signal Amplification (TSA™) reagent. Optimal concentrations and conditions may vary.
