Abstract: The present disclosure provides compositions comprising nucleic acid single-stranded splint strands, including kits, and methods that employ the single-stranded splint strands. The single-stranded splint strands can hybridize to portions of linear library molecules to form circularized library-splint complexes having a nick, where the nick can be ligated to form covalently closed circular molecules which can be subjected to downstream amplification and sequencing workflows.
