Abstract
To link IFNγ-secretion levels of epitope-specific T-cells with their TCRαβ, we coated Nanovials with pHLA-I to capture and activate epitope-specific T-cells and their secreted IFNγ, followed by index-sorting and TCRαβ sequencing. We demonstrate that Nanovials are a promising tool to link single epitope-specific TCRαβ clonotypes to the cell's functional properties.
