Hi-Plex for Simple, Accurate, and Cost-Effective Amplicon-based Targeted DNA Sequencing

Pope, B ; Head, SR ; Ordoukhanian, P ; Salomon, DR (Springer, 2018)

Hi-Plex is a suite of methods to enable simple, accurate, and cost-effective highly multiplex PCR-based targeted sequencing (Nguyen-Dumont et al., Biotechniques 58:33–36, 2015). At its core is the principle of using gene-specific primers (GSPs) to “seed” (or target) the reaction and universal primers to “drive” the majority of the reaction. In this manner, effects on amplification efficiencies across the target amplicons can, to a large extent, be restricted to early seeding cycles. Product sizes are defined within a relatively narrow range to enable high-specificity size selection, replication uniformity across target sites (including in the context of fragmented input DNA such as that derived from fixed tumor specimens (Nguyen-Dumont et al., Biotechniques 55:69–74, 2013; Nguyen-Dumont et al., Anal Biochem 470:48–51, 2015), and application of high-specificity genetic variant calling algorithms (Pope et al., Source Code Biol Med 9:3, 2014; Park et al., BMC Bioinformatics 17:165, 2016). Hi-Plex offers a streamlined workflow that is suitable for testing large numbers of specimens without the need for automation.
