Description

The C17.8 antibody reacts with the p40 subunit of IL-12 and IL-23. The C17.8 antibody has been found to neutralize IL-12 and IL-23 bioactivity. For specific neutralization of IL-23 only, please see clone G23-8 (anti-mouse IL-23 p19). IL-12 is a 70 kDa heterodimeric cytokine composed of two covalently linked chains, p40 and p35, and is secreted by activated monocytes, macrophages, and dendritic cells. IL-23 is a heterodimer composed of the disulfide-linked p19 protein and p40 protein, expressed by activated dendritic cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. The C17.8 antibody has been reported for use in IP, Western, ELISA, neutralization, and intracellular staining for flow cytometric analysis.

Applications Tested

The Functional Grade Purified C17.8 antibody has been tested by LAL assay to verify low endotoxin levels and has been tested for ELISA detection and in bioassay for neutralization of IL-12 p70 and IL-23 bioactivity.

The C17.8 antibody at 62.0 ng/ml has been found to inhibit by 50% the biological effects of 1 ng/ml mouse IL-12 p70 (14-8121) or mouse IL-23 (14-8231), in corresponding bioassay. Detailed information and protocols about cytokine bioassays and in vitro cytokine neutralization using antibodies can be found in the BestProtocols section.
