    V450 Mouse Anti-Human IFN-γ
    V450 Mouse Anti-Human IFN-γ
    Expression of IFN-γ by stimulated human peripheral blood lymphocytes. Human peripheral blood mononuclear cells were stimulated with PMA, Ionomycin in the presence of protein transport inhibitor Monensin GolgiStop™ (Cat. No. 554724). Cells were harvested, fixed and permeabilized using the BD Cytofix/Cytoperm™ Kit (Cat. No. 554714), and stained with APC Mouse Anti-Human CD8 (Cat. No. 555369), PE Mouse Anti-Human CD3 (Cat. No. 555333) and either BD Horizon™ V450 Mouse Anti-Human IFN-γ (Cat. No. 560372; left panel) or BD Horizon™ V450 Mouse IgG1, κ Isotype Control (Cat. No. 560373, right panel). Dot plots were derived from gated events with the forward and side light scatter characteristics of lymphocytes, then gated on CD3 positive events. The quadrant markers for the bivariate dot plots were set based on the isotype controls. Flow cytometry was performed on a BD LSR™ II flow cytometry system.

    Preparation And Storage

    Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. 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.

    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. 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.
    4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
    5. Pacific Blue™ is a trademark of Molecular Probes, Inc., Eugene, OR.
    6. 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.
    7. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
    8. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

    B27

    The B27 monoclonal antibody specifically binds to human interferon-γ (IFN-γ), a 14-18 kDa glycoprotein containing 143 amino acid residues.  IFN-γ is a potent multifunctional cytokine produced by several activated cell types including NK, NKT, CD4+TCRαβ+, CD8+TCRαβ+, and TCRγδ+ T cells. IFN-γ exerts its biological effects through specific binding to the high-affinity IFN-γ receptor complex comprised of IFN-γRα (CD119) and IFN-γRβ subunits. In addition to its antiviral effects, IFN-γ upregulates a number of lymphoid cell functions including the antimicrobial and anti-tumor responses of macrophages, NK cells, and neutrophils. In addition, IFN-γ influences the regulation of proliferation, differentiation, and effector responses of B cell and T cell subsets. These influences can involve IFN-γ's capacity to boost MHC class I and II expression by antigen-presenting cells as well as direct effects on B cells and T cells themselves. B27 is a neutralizing antibody. The use of B27 antibody for epitope mapping of human IFN-γ has been described. The B27 antibody has been reported not to bind to denatured IFN-γ.

    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.
