Flow Cytometry Product Notes: Test Sizes: To accommodate multicolor flow cytometry, eBioscience is in the process of reducing test size volumes from 20 µl to 5 µl. Please check your antibody vial for the recommended test size. Fluorochrome Replacements: eBioscience is in the process of replacing all Pacific Blue® and APC-Alexa Fluor® 750 conjugated products with eFluor™ 450 and APC-eFluor™ 780 conjugated products, respectively.
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 biotinylated C17.8 antibody has been tested as the detection antibody in three different sandwich ELISAs, for measurement of mouse IL-12 p70, mouse IL-23, or mouse IL-12 p40 total.
For mouse IL-12 p70 ELISA: The biotinylated C17.8 antibody has been tested as the detection antibody in sandwich ELISA for analysis of mouse IL-12 p70, in combination with the purified C18.2 antibody (14-7122) for capture and recombinant mouse IL-12 p70 (14-8121) as the standard. A suitable range of concentrations of this antibody for ELISA detection is 0.5-2 µg/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 2,000 pg/ml - 15 pg/ml should be included in each ELISA plate. Super AquaBlue or ABTS are suitable substrates.
For mouse IL-23 ELISA: The biotinylated C17.8 antibody has been tested as the detection antibody in a sandwich ELISA for analysis of mouse IL-23 protein levels, in combination with the purified G23-8 antibody (14-7232) for capture and recombinant mouse IL-23 (14-8231) as the standard. A suitable range of concentrations of this antibody for ELISA detection is 0.25 - 1.0 µg/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 4,000 pg/ml - 30 pg/ml should be included in each ELISA plate. Note: TMB (00-4201), rather than ABTS, should be used as the substrate.
For mouse IL-12 p40 Total ELISA: The biotinylated C17.8 antibody has been tested as the detection antibody in a sandwich ELISA for analysis of mouse total p40 (e.g., p40 monomer, p40 dimer, p40/p35, and p40/p19), in combination with the purified C15.6 antibody (14-7125) for capture and recombinant mouse IL-12 p40 (14-8122), IL-12 p70 (14-8121) or mouse IL-23 (14-8231) as the standard. A suitable range of concentrations of this antibody for ELISA detection is 0.5-2 µg/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 2,000 pg/ml - 15 pg/ml should be included in each ELISA plate. Super AquaBlue or ABTS are suitable substrates.
