Sgourakis TI - High Throughput pMHC-I Tetramer Library Production Using Chaperone Mediated Peptide Exchange AID - 10.1101/653477 DP - 2019 Jan 01 TA - bioRxiv PG - 653477 4099 - http://biorxiv.org/content/early/2019/05/30/653477.short 4100 - http://biorxiv.org/content/early/2019/05/30/653477.full AB - Peptide exchange technologies are essential for the generation of pMHC-multimer libraries, used to probe highly diverse, polyclonal TCR repertoires. Using the molecular chaperone TAPBPR, we present a robust method for the capture of stable, empty MHC-I molecules which can be readily tetramerized and loaded with peptides of choice in a high-throughput manner. Combined with tetramer barcoding using multi-modal cellular indexing technology (ECCITE-seq), our approach allows a combined analysis of TCR repertoires and other T-cell transcription profiles together with their cognate pMHC-I specificities in a single experiment.
