Abstract: A method for determining an efficiency of target enrichment from a DNA library, includes: adding a negative control sequence and a positive control sequence to the DNA library, or picking a negative control sequence and/or a positive control sequence from the library; determining a pre-capture amount of the negative control sequence and a pre-capture amount of the positive control sequence; performing enrichment of a target sequence from the DNA library using a bait sequence to produce a post-capture library; determining a post-capture amount of the negative control sequence and a post-capture amount of the positive control sequence in the post-capture library; and determining the efficiency of the target enrichment, based on the post-capture amount of the positive control sequence, the post-capture amount of the negative control sequence, the pre-capture amount of the positive control sequence, and the pre-capture amount of the negative control sequence.

Abstract: The invention provides methods, compositions and kits for generating a signal indicative of the presence of a target nucleic acid sequence in a sample comprising forming a cleavage structure by incubating a sample comprising a target nucleic acid sequence with upstream and downstream oligonucleotides, and cleaving the cleavage structure with a nuclease to generate a signal. The presence of a detectable signal is indicative of the presence of a target nucleic acid sequence and a non-invasive cleavage structure.

Abstract: The invention relates to compositions and methods for detection of nucleic acid sequences. The invention further relates to kit format of said compositions for detection of nucleic acid sequences. Oligonucleotide probes of the invention comprise a target binding sequence and a sequence at least partially complementary thereto, joined by an optional linker to form a hairpin structure in the absence of the target nucleic acid sequence. The probes of the invention comprise a pair of moieties that produce a detectable signal when the probe hybridizes to the target sequence.

Abstract: The present invention provides composition and methods for the detection and measurement of target nucleic acids. The probes of the present invention, or triplex probes, comprise a complex of three oligonucleotide probes including: (1) a first oligonucleotide probe, (2) a second oligonucleotide probe, and (3) a bridging oligonucleotide probe. In most aspects of the invention, the first and second oligonucleotide probes preferentially hybridize to the bridging oligonucleotide in the absence of a target nucleic acid. The first oligonucleotide probe contains one member of an interactive pair of labels and the second oligonucleotide probe contains the other member of the interactive pair of labels. Separation of the first and second oligonucleotide probes (e.g., binding to target, cleavage of first, second, or bridging oligonucleotide) generates a detectable signal indicating the presence of a target nucleic acid.
