IL-18 antibody (AA 1-157)

Catalog No. ABIN964783

Product Details anti-IL-18 Antibody

Target: IL-18 (IL18) (Interleukin 18 (IL18))

Binding Specificity: AA 1-157

Reactivity: Mouse

Host: Rabbit

Clonality: Polyclonal

Conjugate: This IL-18 antibody is un-conjugated

Application: Western Blotting (WB), ELISA, Immunoprecipitation (IP), Flow Cytometry (FACS), Radioimmunoassay (RIA), Neutralization (Neut)

Specificity: This is an IgG preparation of whole rabbit serum purified by protein A chromatography using a low endotoxin methodology. This antibody is primarily directed against mature 18,000 MW mouse IL-18 and is useful in determining its presence in various assays. This antibody will also recognize the 24,000 inactive precursor form of mouse IL-18. In general, this antibody also detects rat IL-18 in the same formats using similar dilutions. A control of similarly diluted LOW ENDOTOXIN CONTROL RABBIT IgG (code # 011-001-297) is recommended.

Characteristics: Interleukin-18 (IL-18) is a member of the IL-1 cytokine family and was initially identified as an Interferon-g (IFN-g) inducing factor (IGIF). The IL-18 gene was originally cloned from liver cells and has since been shown to be produced by activated monocytes/ macrophages, Kupffer cells, keratinocytes, glucocorticoid-secreting adrenal cortex cells, osteoblasts and dendritic cells. IL-18 is a 24 kDa, non-glycosylated polypeptide that lacks a classical signal sequence and possesses a structure recognizably similar to IL-1. IL-18 is synthesized as a bio-inactive propeptide that undergoes proteolytic cleavage by either ICE (interleukin-1 beta converting enzyme) or another caspase to generate a mature, bioactive, 18 kDa molecule. In both the mature and propeptide forms, IL-18 shows 64% aa sequence identity from mouse to human. IL-18 does not appear to show any primary sequence similarity to any other known cytokines. Rat IL-18 has also been isolated, and found to be 194 aa in length with a 91% aa sequence identity to mouse IL-18. Human IL-18 has been found to induce the production of IFN-g and GM-CSF while inhibiting the production of IL-10 by PBMC. With respect to human T cells, IL-18 enhances Th1 cytokine production and stimulates cell proliferation via an IL-2-dependent pathway. Human IL-18 can also inhibit the synthesis of IgE by B cells. Thus, IL-18 plays an important role in immunological and inflammatory reactions. Currently, the bioactivity of human IL-18 is often determined by its capacity to augment the levels of IFN-g produced by T cells as measured in tissue culture supernatants.

Sterility: Sterile filtered

Immunogen: The whole rabbit serum used to produce this IgG fraction antibody was prepared by repeated immunizations with native 157 aa mouse IL-18 produced in E.coli.
Immunogen Type: Recombinant Protein

Isotype: IgG

Application Details

Application Notes: This IgG fraction antibody of anti-Mouse IL-18 has been tested for use in neutralizations, ELISA, immunohistochem-istry and immunoblotting. Although untested, this reagent may be useful for radioimmunoassays, flow cytometry and immunoprecip-itation. It recognizes the 18,000 MW mature (active) IL-18. Reactivity in other immunoassays is unknown.
