Our Abpromise guarantee covers the use of ab9722 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||WB: Use at an assay dependent dilution. To detect mIL-1b 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 mIL-1b is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.|
|ELISA||ELISA: Use at an assay dependent dilution. To detect mIL-1b by direct ELISA (using 100µl/well antibody solution) a concentration of at least 0.5µg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2 - 0.4 ng/well of recombinant mIL-1b.|
|Neutralising||Neut: Use at an assay dependent dilution. To yield one-half maximal inhibition [ND50] of the biological activity of mIL-1b (50 pg/ml), a concentration of 100 - 150 ng/ml of this antibody is required.|
|IHC-P||IHC-P: Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
|IHC-Fr||IHC-Fr: Use at an assay dependent dilution. PubMed: 18420712Acetone fixed.|
|IHC-FoFr||IHC-FoFr: Use at an assay dependent concentration.|
|ICC/IF||ICC/IF: Use at an assay dependent concentration.|
- FunctionProduced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells.
- Sequence similaritiesBelongs to the IL-1 family.
- DomainThe similarity among the IL-1 precursors suggests that the amino ends of these proteins serve some as yet undefined function.
- Cellular localizationSecreted. The lack of a specific hydrophobic segment in the precursor sequence suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.

ab9722 staining IL1 beta in murine bone marrow-derived macrophages by Immunocytochemistry/ Immunofluorescence. Cells are immortalised murine bone marrow-derived macrophages stably transfected with GFP-LC3 (green) to visualise autophagosomes. The cells were fixed in paraformaldehyde, permeabilised in 0.01% Triton X-100 and then blocked using 5% serum for 1 hour at 20°C. Samples were then incubated with primary antibody at 1/200 for 1 hour at 20°C. The secondary antibody used was a goat anti-rabbit IgG conjugated to Alexa Fluor® 568 (red) used undiluted.
ab9722 staining IL1 beta in rat brain tissue sections by Immunohistochemistry (PFA perfusion fixed frozen sections).
Tissue was fixed with paraformaldehyde and blocked with 10% serum for 1 hour at 25°C. Samples were incubated with primary antibody (1/100 in diluent) for 10 hours at 25°C. An AlexaFluor®555-conjugated donkey anti-goat IgG polyclonal (1/300) was used as the secondary antibody.
ab9722 staining IL1 beta (green) in murine macrophage cells by Immunocytochemistry/ Immunofluorescence.
Cells were fixed with formaldehyde, permeabilized with 0.1% Triton X-100 + 3% BSA and blocked with 3% BSA for 3 hours at 25°C. Samples were incubated with primary antibody (1/100 in 1% BSA in PBS) for 1 hour at 25°C. A FITC-conjugated goat anti-rabbit polyclonal IgG (1/100) was used as the secondary antibody. Nuclei were stained with DAPI (blue).
IHC image of IL1 beta staining in mouse kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab9722, 1µg/ml, for 15 mins at room temperature. A goat anti-rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
Immunohistochemical analysis of PFA perfusion fixed frozen mouse brain, staining IL1 beta (green) with ab9722 at 0.5 µg/ml. A peroxidase conjugated secondary antibody was used and staining was detected using a fluorescein Tyramide Signal Amplification (TSA™) reagent.
