    V450 Mouse Anti-Human IL-12 (p40/p70)
    Expression of IL-12 (p40/p70) by stimulated human monocytes. Human peripheral blood mononuclear cells were primed for 2 hours with recombinant human IFN-γ (Cat. No. 554616/554617; 10 ng/ml final concentration). The cells were then activated with IFN-γ (10 ng/ml final concentration) and LPS (100 ng/ml final concentration) in the presence of GolgiStop™ (Cat. No. 554724) for an additional 22 hours. The cells were fixed using BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained with PE Mouse Anti-Human CD14 (Cat No. 555398) and BD Horizon™ V450 Mouse Anti-Human IL-12 (p40/p70) (Cat No. 561380, Left Panel) or BD Horizon™ V450 Mouse IgG1 κ Isotype Control (Cat No. 560373, Right Panel) by using BD Biosciences Intracellular Cytokine Staining protocol. Two-color flow cytometric dot plots showing the correlated expression of IL-12 (p40/p70) (or Ig Isotype Control Staining) versus CD14 were derived from events with the forward and side light-scatter characteristics of intact monocyte/macrophages. HiCK-3 Human Cytokine Positive Control cells (Cat No. 555063) are prepared in a similar manner. These cells can be used as a positive control for cytokine flow cytometry experiments designed to characterize the nature of human IL-12 (p40/p70)-producing cells. Flow cytometry was performed using a BD™ LSR II Flow Cytometer System.

    Preparation And Storage

    The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon™ V450 under optimum conditions, and unreacted BD Horizon™ V450 was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

    Product Notices

    1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
    2. An isotype control should be used at the same concentration as the antibody of interest.
    3. Pacific Blue™ is a trademark of Molecular Probes, Inc., Eugene, OR.
    4. BD Horizon V450 has a maximum absorption of 406 nm and maximum emission of 450 nm. Before staining with this reagent, please confirm that your flow cytometer is capable of exciting the fluorochrome and discriminating the resulting fluorescence.
    5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
    6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

    C11.5

    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.

    The antibody is conjugated to BD Horizon™ V450, which has been developed for use in multicolor flow cytometry experiments and is available exclusively from BD Biosciences. It is excited by the Violet laser Ex max of 406 nm and has an Em Max at 450 nm. Conjugates with BD Horizon™ V450 can be used in place of Pacific Blue™ conjugates.

    V450
    BD Horizon™ V450 Dye is part of the BD Horizon™ violet family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 405-nm and an emission maximum (Em Max) at 450-nm. BD Horizon™ V450, driven by BD innovation, is designed to be excited by the violet laser (405 nm) and detected using an optical filter centered near 450-nm (e.g., a 450/50-nm bandpass filter). The dye can be excited by the UV (355-nm) laser resulting in cross-laser excitation and spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
