V450 Rat Anti-Mouse IFN-γ
V450 Rat Anti-Mouse IFN-γ

Flow cytometric analysis for IFN-γ in activated mouse splenocytes.  Mouse Intracellular Cytokine-1 positive control cells (MiCK-1) offered by BD Biosciences as MN 554652, are activated mouse splenocytes prepared in the presence of a protein transport inhibitor.  Fixed and permeabilized MiCK-1 cells were stained either with a BD Horizon™ V450 Rat IgG1, κ isotype control (left panel) or with the BD Horizon™ V450 Rat Anti-Mouse IFN-γ antibody (right panel).  Dot plots were derived from gated events based on light scattering characteristics for lymphocytes.  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.

Recommended Assay Procedures

Flow cytometry:  The XMG1.2 antibody is useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IFN-γ producing cells within mixed cell populations.  A useful control investigators may consider using for demonstrating specificity of staining, is to pre-block with one of the following reagents: (1) recombinant mouse IFN-γ (Cat. No. 554587) or (2) unlabeled XMG1.2 antibody (Cat. No. 554409), prior to staining.

Cell Preparation: Investigators not wishing to utilize MiCK-1 cells may alternatively prepare mouse splenocytes (e.g BALB/c) stimulated for 4-6 hours with PMA (5 ng/mL, Sigma-Aldrich Cat. No. P-8139) and ionomycin (500 ng, Sigma-Aldrich Cat. No. I-0634) in the presence of 1 µg/mL Brefeldin A (BD GolgiPlug™ MN 555029).  Investigators are advised to fix and permeabilize the cells prior to staining.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. 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.

XMG1.2

The XMG1.2 monoclonal antibody specifically binds to mouse interferon-γ (IFN-γ) protein. IFN-γ is a pleiotropic cytokine, of approximately 15-17 kDa, involved in the regulation of inflammatory and immune responses. It plays an important role in activation, growth, and differentiation of T and B lymphocytes, macrophages, NK cells and other non-hematopoietic cell types. IFN-γ production is associated with the Th1 cell differentiation. The purified form of this antibody has been reported to be a neutralizing antibody.

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.
