title: A protocol for combining proliferation, tetramer staining and intracellular cytokine detection for the flow-cytometric analysis of antigen specific T-cells.
abstract: Flow-cytometry can be used in different ways in order to analyze or enumerate antigen specific T-cells. The three basic principles are direct staining of the T-cell receptor using so called tetramer reagents, staining intracellular cytokines following antigen-specific ex vivo T-cell activation or staining with dyes that are incorporated (increase in staining) or distributed between daughter cells (decrease in staining) upon proliferation in response to a specific antigen challenge. Each system has its advantages and disadvantages. Here we demonstrate that tetramer staining, cytokine flow cytometry and staining with CFDA-SE can be combined permitting the analysis of proliferation and cytokine production with a subset of T-cells specific for a single peptide antigen.
