APC-R700 Mouse Anti-Human IFN-γ

Two-color flow cytometric analysis of IFN-γ expression in stimulated human peripheral blood mononuclear cells. HiCK-1 Human Cytokine Positive Control Cells (Cat. No. 555061) were permeabilized with BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained with PE Mouse Anti-Human CD3 antibody (Cat. No. 561808/555333/561809) and either no antibody (Autofluorescence Control; Left Panel) or BD Horizon APC-R700 Mouse Anti-Human IFN-γ antibody (Cat No. 564981; Right Panel). Two-color flow cytometric contour plots showing the expression of IFN-γ (or cellular autofluorescence) versus CD3 were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer 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 APC-R700 under optimum conditions, and unconjugated antibody and free BD Horizon APC-R700 were 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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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.

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.

This antibody was conjugated to BD Horizon APC-R700, which has been developed exclusively by BD Biosciences as a better alternative to Alexa Fluor® 700. APC-R700 excites and emits at similar wavelengths to Alexa Fluor® 700 yet exhibits significantly improved brightness. This dye can be excited by the red laser and detected with the same filter set as Alexa Fluor® (eg, 730/45-nm filter).

APC-R700
The BD Horizon™ APC-R700 (APC-R700) Dye is a part of the BD APC red family of dyes. This tandem fluorochrome is comprised of an Allophycocyanin (APC) dye donor that has excitation maximum (Ex Max) of 651-nm and an acceptor dye, R700, with an emission maximum (Em Max) at 706-nm. APC-R700, driven by BD innovation, is designed to be excited by the red (627–640-nm) laser and detected using an optical filter centered near 710-nm (e.g., a 720/40-nm bandpass filter). APC-R700 is a brighter alternative to Alexa Fluor™ 700. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
