Abstract: The present disclosure provides a method for enrichment of at least one target nucleic acid in a library of nucleic acids. A first oligonucleotide is hybridized to a target nucleic acid in library of nucleic acids having first and second adapters. The hybridized first oligonucleotide is extended with a first polymerase, thereby producing a first primer extension complex including the target nucleic acid and the extended first oligonucleotide. The first primer extension complex is captured, enriched relative to the library of nucleic acids, and a second oligonucleotide is hybridized to the target nucleic acid. The hybridized second oligonucleotide is extended with a second polymerase, thereby producing a second primer extension complex including the target nucleic acid and the extended second oligonucleotide, and further liberating the extended first oligonucleotide from the first primer extension complex.

Abstract: The invention is a novel method of making and using a library such as a sequencing library of single stranded circular nucleic acid templates via splint ligation. In particular, disclosed are methods of making circular target nucleic acid molecules and libraries of such molecules for downstream analysis such as nucleic acid sequencing. The method comprises the steps of adding universal sequences to nucleic acid molecules, rendering single-stranded these nucleic acid molecules with universal sequences on their ends by contacting with a probe complementary to at least a portion of the universal sequences, and allowing the hybridized probe to enable circularization and formation of single-stranded circular (sscDNA) molecules.
