The C17.8 antibody reacts with mouse 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 C17.8 antibody can neutralize the bioactivity of natural or recombinant IL-12.Product Details
- Mouse, IL-12/IL-23 p40 subunit (monomer, homodimer and heterodimer IL-12 p35/p40 or IL-23 p19/p40)
- Antibody Type
- Host Species
- CHO expressed, recombinant mouse IL-12 p70
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
- The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions. The solution is free of unconjugated biotin.
- 0.5 mg/ml
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
ELISA Detection, ELISPOT Detection, ICFC
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. For use as an ELISA detection antibody, a concentration range of 0.25-1.0 µg/ml is recommended. For use as an ELISPOT detection antibody, a concentration range of 0.5-2.0 µg/ml is recommended. To obtain a linear standard curve, serial dilutions of IL-12 recombinant protein ranging from 250 to 2 pg/ml are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
ELISA Detection1,2,6-9 or ELISPOT Detection: The biotinylated C17.8 antibody is useful as a detection antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with the purified C15.6 antibody (Cat. No. 505202/505208) as capture antibody and recombinant mouse IL-12/IL-23 p40 (Cat. No. 576909) or recombinant mouse IL-12 p70 (Cat. No. 577009) as the standard.
Neutralization1,2,4,5,6,10: The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for neutralization of mouse IL-12 bioactivity in vivo and in vitro (Cat. No. 505304). For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 505308) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).
Additional reported applications (for relevant formats of this clone) include: Western blotting3, immunoprecipitation3, and intracellular immunofluorescent staining and flow cytometric analysis.
Note: For testing mouse IL-12 p40 (monomer, dimer, heterodimer) in serum or plasma, BioLegend's ELISA Max™ Sets (Cat. No. 431601 to 431606) are specially developed and recommended.
