Abstract
The disclosure provides methods and reagents for preparing DNA libraries from biological materials for targeted sequencing. The approach can enhance the efficiency and sensitivity of targeted sequencing applications, such as liquid biopsy analyses to assess genetically driven conditions. In an embodiment, the disclosed method comprises attaching the 5' end of an oligonucleotide adapter to the 3′ end of double-stranded DNA fragment to produce an adapter/fragment chimeric molecule; producing at least one complementary strand of the adapter/fragment chimeric molecule by linear amplification; hybridizing the at least one complementary strand with an oligonucleotide probe, wherein the oligonucleotide probe comprises a hybridization domain with a sequence that hybridizes to a target sequence in the complement strand to produce a targeted complement strand/probe duplex; purifying the targeted complement strand/probe duplex; and extending the probe in the purified targeted complement strand/probe duplex and amplifying with PCR to produce a plurality of sequencing template molecules.
