Patent ID: 10240198

Abstract:
Provided herein, among other things, is a method of processing a nucleic acid sample. In some embodiments, the method comprises a) hybridizing a sample comprising a target fragment to a nucleic acid probe comprising: i. a head sequence and a tail sequence, wherein the head and tail sequences are at the ends of a first oligonucleotide molecule; and ii. a splint sequence comprising, in order: an upstream flanking sequence that is complementary to the head sequence; a target complementary sequence that is complementary to the target fragment; and a downstream flanking sequence that is complementary to the tail sequence; thereby producing a hybridization product in which the ends of the target fragment are ligatably adjacent to the ends of the head and tail sequences in the first oligonucleotide molecule; and b) ligating the ends of the target fragment to the ends of the head and tail sequences of the first oligonucleotide molecule, thereby producing a cyclic product that comprises the target fragment and the head and tail sequences. Probes and kits for performing the method are also provided.
