The C8.6 antibody reacts with human IL-12 p40 subunit of the IL-12 p70 heterodimer and IL-23 p40 subunit of the IL-23 p19/p40, as well as p40 monomer and homodimer. The C8.6 antibody has been reported to strongly inhibit different biological activities of IL-12, (e.g., IFN-gamma induction, mitogenic effects on PHA blasts, and enhancement of NK cell-mediated cytotoxicity). The C8.6 antibody can neutralize the bioactivity of natural or recombinant IL-12.Product Details

ELISA Detection, ELISPOT Detection
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. For ELISA detection applications, a concentration range of 0.5-2.0 µg/ml is recommended. To obtain a linear standard curve, serial dilutions of IL-12 p40 recombinant protein ranging from 4000 to 30 pg/ml are recommended for each ELISA plate. To obtain a linear standard curve, serial dilutions of IL-12 p70 recombinant protein ranging from 1000 to 8 pg/ml are recommended for each ELISA plate. For use as an ELISPOT detection antibody, a concentration range of 1-4 µg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
ELISA or ELISPOT Detection1,2: The biotinylated C8.6 antibody is useful as a detection antibody for an IL-12 p40 specific sandwich ELISA or ELISPOT assay, when used in conjunction with the C8.3 antibody (Cat. No. 501702/501704) as the capture antibody. The biotinylated C8.6 antibody is useful as a detection antibody for an IL-12 p70 specific sandwich ELISA or ELISPOT assay, when used in conjunction with the Purified 7B12 antibody (Cat. No. 511002/511004) as the capture antibody. Each lot of this antibody is quality control tested by ELISA assay.
Neutralization1,3,4: The LEAF™Purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for neutralization of human IL-12 bioactivity (Cat. No. 508804).
