Direct Capture, Amplification and Sequencing of Target DNA Using Immobilized Primers

摘要

Certain embodiments provide a method for capturing a genomic fragment. The method may comprise: obtaining a substrate comprising a first population of surface-bound oligonucleotides and a second population of surface-bound oligonucleotides; hybridizing a first member of the first population of surface-bound oligonucleotides to a selection oligonucleotide comprising a region that hybridizes with the first member and a region that contains a genomic sequence; extending the first member of the first population of surface-bound oligonucleotides to produce a support-bound selection primer that comprises a sequence that is complementary to the genomic sequence; hybridizing the support-bound selection primer to a nucleic acid fragment comprising the genomic sequence; extending the support-bound selection primer to produce an extension product that contains a sequence that flanks the genomic sequence, e.g., in a genome; and amplifying the extension product on the substrate.
