Human PBMC (15,000 cells / well) were incubated for 5 hours in the absence or presence of either 1X Cell Activation Cocktail (without Brefeldin A) (Cat. No. 423301) or 1X Cell Activation Cocktail (with Brefeldin A) (Cat. No. 423303). BioLegend’s Cell Activator cocktail contains PMA and ionomycin at the optimized concentration. Brefeldin A functions to inhibit intracellular protein transport, as a result, it inhibits secretion of cytokines such as IFN-γ. The number of cells secreting Human IFN-γ was analyzed by FluoroSpot and quantified using an image cytometer equipped with the required fluorescence filter.

Human IFN-γ (Interferon-gamma) is a multifunctional cytokine which is the sole member of the class II Interferon. Although a variety of immune cells can express IFN-γ, most of IFN-γ is produced by T cells and NK cells. It has critical roles in many processes including, but not limited to, anti-viral response, regulating Th1/Th2 balance, enhancing antigen presentation, and controlling cellular proliferation and apoptosis. IFN-γ can bind to 2 receptors: IFNGR1 and IFNGR2, which transduce the signal downstream through the JAK-STAT pathway. Because of its multifunctional nature, dysregulation of IFN-γ expression and activity has been implicated in many diseases such as autoimmune and cancer.
BioLegend’s FluoroSpot MAX™ Deluxe Set contains pre-optimized essential reagents, buffers, and solutions for the detection of human IFN-γ secreting cells. In this assay, anti-human IFN-γ capture antibodies are coated on a clear-bottom microplate. Cells (stimulated or unstimulated) are
added to the wells and incubated, allowing secreted IFN-γ to bind to nearby capture antibodies. After incubation, cells are removed, and biotinylated
detection antibodies are added followed by Streptavidin-PE. The resulting red spots represents the “footprint” of an individual IFN-γ-secreting cell, allowing for precise quantification of cytokine-producing cells in the sample.
