Full-Length RNA-seq of Alzheimer brain on the PacBio Sequel II System

The PacBio Iso-Seq method produces high-quality, full-length transcripts and can characterize a whole transcriptome with a single SMRT Cell 8M. We sequenced an Alzheimer whole brain sample on a single SMRT Cell 8M on the Sequel II System. Using the Iso-Seq bioinformatics pipeline followed by SQANTI2 analysis, we detected 162,290 transcripts for 17,670 genes up to 14 kb in length. More than 60% of the transcripts are novel isoforms, the vast majority of which have supporting cage peak data and polyadenylation signals, demonstrating the utility of long-read sequencing for human disease research.
