Abstract:
Ab repertoire sequencing is a powerful tool to analyze the adaptive immune system. To sequence entire Ab repertoires, amplicons are created from Ab H chain (IgH) transcripts and sequenced on a high-throughput sequencer. The field of immune repertoire sequencing is growing rapidly and the protocols used are steadily improving; however, thus far, immune repertoire sequencing protocols have not been able to sequence full-length immune repertoires including the entire IgH V region and enough of the IgH C region to identify isotype subtypes. In this study, we present a method that combines Tn5 transposase and molecular identifiers for the highly accurate sequencing of amplicons >500 bp using Illumina short read paired-end sequencing. We then apply this method to Ab H chain amplicons to sequence the first, to our knowledge, highly accurate full-length immune repertoire.
