摘要: The present invention provides nucleic acid based polymerase inhibitors and methods for reducing non-specific polymerase extension and amplification in nucleic acid amplification reactions. The polymerase inhibitors provide a double stranded nucleic acid portion that is recognized by a polymerase enzyme as a template for extension but is incapable of being extended by the polymerase enzyme. The polymerase binds to the polymerase inhibitor which sequesters the enzyme until the temperature achieves a level that denatures the double stranded portion of the inhibitor after which the polymerase is released and can then catalyze nucleic acid extension.

摘要: Solid support assays using non-standard bases are described. A capture oligonucleotide comprising a molecular recognition sequence is attached to a solid support and hybridized with a target. In some instances, the molecular recognition sequence includes one or more non-standard bases and hybridizes to a complementary tagging sequence of the target oligonucleotide. In other instances, incorporation of a non-standard base (e.g., via PCR or ligation) is used in the assay.

摘要: Assays using non-natural bases are described. In one embodiment, the method involves contacting a sample suspected of containing the target nucleic acid with a polymerase and first and second primers; amplifying the target nucleic acid, if present in the sample, by PCR using the first and second primers to generate an amplification product having a double-stranded region and a single-stranded region that comprises the non-natural base; contacting the sample with a reporter comprising a label and a non-natural base that is complementary to the non-natural base of the single-stranded region; annealing at least a portion of the reporter to the single-stranded region of the amplification product; cleaving, after annealing, at least a portion of the reporter to release at least one reporter fragment; and correlating the release of the at least one reporter fragment with the presence of the target nucleic acid in the sample. The invention also provides corresponding kits for use in detecting target nucleic acids in a sample. Alternatively, the reporter can be incorporated into the amplification product rather than annealing and then cleaving.
