What antigen(s) does each T cell bind to?
What TCR sequences does each T cell have?
What are the phenotype and function of each T cell?
Our Solution
We developed TetTCR-Seq, a platform for high-throughput pairing of TCR sequences with potentially multiple pMHC species bound on single T cells.
Library of fluorescently labeled, DNA-barcoded pMHC tetramers is constructed using in vitro transcription & translation.
Tetramer-stained cells are single-cell sorted to amplify the DNA-barcoded (with molecular identifier) and TCRαβ genes in RT-PCR.
Nucleotide-based cell barcodes are used to link multiple peptide specificities with their bound TCRαβ sequences.
