Abstract: Disclosed, for example, are methods comprising cleaving an uncleaved probe to form a cleaved oligonucleotide flap, forming a hybridization complex between the cleaved oligo-nucleotide flap, a bridging oligonucleotide, and a capture oligonucleotide that is immobilized on a surface, such that the oligonucleotide flap and the capture oligonucleotide are hybridized to immediately adjacent, complementary regions of the bridging oligonucleotide, ligating the oligonucleotide flap to the capture oligonucleotide to form an immobilized ligation product, and detecting the ligation product.

Abstract: Disclosed, for example, are methods for detecting at least one target polynucleotide comprising cleaving a flap from a polynucleotide probe that is hybridized to a complementary target polynucleotide, and hybridizing the cleaved flap to a complementary capture probe immobilized on a surface, wherein said cleaving and/or hybridizing occurs in the presence of a single strand binding protein that is capable of binding single-stranded DNA, but that can bind neither the flap nor the capture probe. The cleaved flap and the complementary capture probe may each comprise PNA, RNA, LNA, L-DNA or other modified nucleotides or chimeras thereof that do not significantly bind to the single strand binding protein.
