Targeted sequencing using a long-read sequencing technology

Author(s): McLaughlin, I., and Baybayan, P., and Hall, R., and Harting, J., and W. Rowell

Targeted sequencing employing PCR amplification is a fundamental approach to studying human genetic disease. PacBio’s Sequel System and supporting products provide an end-to-end solution for amplicon sequencing, offering better performance to Sanger technology in accuracy, read length, throughput, and breadth of informative data. Sample multiplexing is supported with three barcoding options providing the flexibility to incorporate unique sample identifiers during target amplification or library preparation. Multiplexing is key to realizing the full capacity of the 1 million individual reactions per Sequel SMRT Cell. Two analysis workflows that can generate high-accuracy results support a wide range of amplicon sizes in two ranges from 250 bp to 3 kb and from 3 kb to >10 kb. The Circular Consensus Sequencing workflow results in high accuracy through intra-molecular consensus generation, while high accuracy for the Long Amplicon Analysis workflow is achieved by clustering of individual long reads from multiple reactions. Here we present workflows and results for single- molecule sequencing of amplicons for human genetic analysis.
