273449 Award Submission: High Throughput Sequencing of Antibody Heavy and Light Chain Pairings
Next generation DNA sequencing (NGS) is transforming the field of immunology by giving researchers the potential to sequence immune repertoires at unprecedented depth. However, the utility of NGS for repertoire analysis is severely curtailed by its inability to resolve the pairing between antibody heavy and light chains and T-cell receptor α and β strands. To directly address this issue, we have developed an emulsion-based method to sequence natively paired antibody heavy and light chains at high-throughput. VH-VL pairings have been validated using mixtures of various immortalized B-cell clones with known antibody sequences to confirm accuracy. High-throughput sequencing of the heavy and light chain pairing is a significant step toward greater understanding of the immune repertoire, and potential applications include immune response analysis and antibody discovery.
