Determining the antigen specificities of the endogenous T-cell repertoire is important for screening naturally occurring or therapy-induced T-cell immunity and may help identify novel targets for T-cell-based therapies. Here, we describe a rapid, sensitive, and high-throughput protocol for expanding antigen-specific T cells from human peripheral blood mononuclear cells in vitro following peptide stimulation and detecting antigen-specific effector cytokine formation by flow cytometry. Our approach can be applied to examining specific T-cell subsets from various tissues. For complete details on the use and execution of this protocol, please refer to Roudko et al. (2020) and Cimen Bozkus et al. (2019).
