We have evaluated the Adaptive Focused Acoustics (AFA™) system by Covaris as a method for obtaining high molecular weight DNA suitable for SMRTbell template preparation and subsequent single molecule sequencing. Using this method, genomic DNA was extracted from normal kidney FFPE scrolls acquired from Cooperative Human Tissue Network (CHTN), University of Pennsylvania. Damaged sites present in the extracted DNA were repaired using a DNA Damage Repair step, and the treated DNA was constructed into SMRTbell libraries suitable for sequencing on the PacBio RS II System. Using the same repaired DNA, we also tested PCR efficiency of target gene regions of up to 5 kb. The resulting amplicons were constructed into SMRTbell templates for full-length sequencing on the PacBio RS II System. We found the Adaptive Focused Acoustics (AFA) system combined with truXTRAC™ by Covaris to be effective and efficient. This system is easy and simple to use, and the resulting DNA is compatible with SMRTbell library preparation for targeted and whole genome SMRT Sequencing. The data presented here demonstrates single molecule sequencing of DNA samples extracted from tissues embedded in FFPE.
