    摘要: The present invention provides methods, kits, and compositions for the detection of an analyte. The invention is particularly suited for the detection and quantification of an analyte in a sample. In the methods of the invention a complex is formed between an analyte specific binding agent and an analyte. The analyte specific agents are coupled to an enzyme possessing an activity that produces a PCR template indicative of the presence of the analyte. Amplification and detection of the PCR template yields a sensitive and quantitative measurement of analyte concentration.

    摘要: The subject invention provides for a method of selectively cloning homoduplex nucleic acid molecules, in particular, by using a strain of host cells that contains a conditionally expressed and/or conditionally active mismatch-recognizing enzyme, e.g., a temperature sensitive variant of the gene encoding the endonuclease VII from phage T4. Using this host strain, the invention features a novel cloning method that selects for PCR products that are devoid of PCR-generated mutations.

    摘要: Provided herein are methods, compositions and kits for detecting a target nucleic acid. A target nucleic acid can be produced, for example, by a cleavage reaction in an assay for detection of biological samples. In one aspect, a described method comprises the following steps: hybridizing the target nucleic acid having a 5′ end and a 3′ end to a probe to form a circular hybridization complex; forming a covalent circular target nucleic acid using the probe as a template for nucleic acid synthesis; and detecting the covalent circular target nucleic acid.

    摘要: The present invention provides methods, kits and compositions for the detection of an analyte. The invention is particularly suited for the detection and quantification of analytes in solution. In the methods of the invention a complex is formed between two or more analyte specific probes (ASP) and an analyte. The reactive moieties of the probes interact upon the binding of the analyte specific probes to the analyte. The reactive moieties generate a nucleic acid cleavage product which is detected and indicative of the presence of the analyte.

    摘要: The invention provides a method of generating a signal indicative of the presence of a target nucleic acid sequence in a sample by forming a cleavage structure by incubating a sample comprising a target nucleic acid sequence with a probe, nucleic acid polymerase, nuclease and optionally a primer. The target nucleic acid is extended and circularized and a cleavage structure is formed. The cleavage structure is cleaved with a nuclease to generate a nucleic acid fragment which is indicative of the presence of a target nucleic acid sequence in the sample.
