Flow cytometric comparison of different clones for IFN-y. Human peripheral blood mononuclear cells (PBMCs) were stimulated with 20 ng/mL Phorbol 12-myristate 13-acetate (PMA) and 1 µg/ml Ionomycin for 1 hour, followed by an incubation with 1µg/mL Brefeldin A for 4 hours. Cells were stained with a suitable counterstaining and then fixed and permeabilized followed by a staining with IFN-y antibodies. As a control, IFN-y antibody staining was omitted and cells were measured in the same channels. Flow cytometry was performed with the MACSQuant^® Analyzer. CD3⁺ cells were pregated for the analysis. Cell debris and cell doublets were excluded from the analysis based on scatter signals. No FcR Blocking Reagent was used. The recommended titers of respective antibodies from different suppliers were used.

Overview

Interferon gamma (IFN-γ) is produced by cells that are involved in inflammatory immune responses. IFN-γ is predominantly released by memory and effector CD4

⁺

and CD8

⁺

T cells as well as by NK cells upon activation. Quantitative analysis of IFN-γ–producing cells can provide important information on the course of immune responses. Anti-IFN‑γ antibodies are designed for intracellular staining of IFN‑γ–producing cells. Cells can be stimulated for IFN-γ–production, e.g. by polyclonal stimulation with mitogens. For induction of IFN‑γ–production by antigen-specific T cells, cells are restimulated with respective antigen. IFN‑γ can be accumulated in the cells by addition of secretion inhibitors like brefeldin A. After fixation and permeabilization of the cell sample, IFN‑γ–producing cells can be stained intracellularly with Anti-IFN‑γ antibodies. Staining of surface markers allows simultaneous flow cytometric analysis of subsets and activation status of the IFN-γ–producing cells.
