抗原名称
IL-12
宿主
Mouse IgG1
免疫原
CHO-expressed recombinant human IL-12 p70 heterodimer
简单描述
The C11.5 monoclonal antibody specifically binds to the human IL-12 p40 monomer and p70 heterodimer, but does not bind to the IL-12 p35 monomer. The immunogen used to generate the C11.5 hybridoma was the CHO-expressed recombinant human IL-12 p70 heterodimer.  p40 has also been described as a subunit of IL-23 and thus it is possible that the C11.5 antibody crossreacts with IL-23. This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

FITC
Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Expression of IL-12 p40/p70 by activated CD14 + human PBMCs. Ficoll™-separated human PBMCs were primed for 2 hours with recombinant human IFN-γ (10 ng/ml final concentration; Cat. No. 554616), then activated with IFN-γ (10 ng/ml final concentration) and LPS (100 ng/ml final concentration; Sigma) in the presence of GolgiStop™ (2 µM final concentration; Cat. No. 554724) for an additional 22 hours. Cells were harvested, stained with PE-mouse anti-human CD14 antibody (Cat. No. 555398), fixed, permeabilized, and then stained with 0.125 µg of FITC-C11.5 antibody (Cat. No. 554574), following the BD Pharmingen staining protocol (left panel). The data reflect gating on monocytes, based on forward and side scattered light signals. To demonstrate specificity of staining, the binding of FITC-C11.5 antibody was blocked by preincubation of the conjugated antibody with recombinant human IL-12 p70 (Cat. No. 554613; middle panel) and by preincubation of the fixed/permeabilized cells with unlabeled C11.5 antibody (Cat. No. 554573; right panel) prior to staining with the FITC-C11.5 antibody. The quadrant markers for the bivariate dot plots were set based on the autofluorescence control, and verified with the recombinant cytokine blocking and unlabelled antibody blocking specificity controls.
