摘要： The present invention provides nucleic acid amplification methods that desirably reduce or eliminate false positive amplification signals resulting from contaminating biological material, e.g., nucleic acid, that may be present in one or more reagents used in an amplification reaction and/or that may be present in the environment in which an amplification reaction is performed. The invention offers the further advantage of requiring less stringent purification and/or sterility efforts than conventionally needed in order to ensure that enzymes and other reagents used in amplification reactions, and the environment in which an amplification reaction is performed, are free of bacterial or other nucleic acid contamination that may yield false positive results.

摘要： The present invention is directed to novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic (i.e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, the present invention discloses a method of nucleic acid amplification which is robust and efficient, while reducing the appearance of side products. The method uses only one primer, the “priming oligonucleotide,” a 3′blocked promoter oligonucleotide and optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or eliminating the formation of side products. The method of the present invention minimizes or eliminates the emergence of side products, thus providing a high level of specificity. Furthermore, the appearance of side products can complicate the analysis of the amplification reaction by various molecular detection techniques. The present invention minimizes or eliminates this problem, thus providing an enhanced level of sensitivity.

摘要： The present invention provides compositions, kits and methods for the selective hybridization and capture of a specific target nucleic acid. The specific target nucleic acid may be present in a heterogeneous mixture of nucleic acids. Selective hybridization and capture provides a target nucleic acid that is substantially free of non-target and/or contaminating nucleic acids. Target nucleic acids that have been selectively hybridized and captured using the current invention are then used in subsequent analysis, wherein the presence of non-target and/or contaminating nucleic acids that interfere with said subsequent analysis have been substantially reduced or eliminated, thereby providing improved analysis results. The invention offers the further advantage of requiring less stringent purification and/or sterility efforts than conventionally needed in order to ensure that enzymes and other reagents used in subsequent analysis, or present in the environment in which an assay is performed, are free of bacterial or other contaminating nucleic acids.

摘要： Kits for amplifying DNA which include a priming oligonucleotide that hybridizes to a 3′-end of a DNA target sequence, a displacer oligonucleotide that hybridizes to a target nucleic acid containing the DNA target sequence at a position upstream from the priming oligonucleotide, and a promoter oligonucleotide that includes a region that hybridizes to a 3′-region of a DNA primer extension product that includes the priming oligonucleotide and a promoter for an RNA polymerase. The priming oligonucleotide does not include an RNA region that hybridizes to the target nucleic acid and is selectively degraded by an enzyme activity when hybridized to the target nucleic acid. The kits do not include a restriction endonuclease and oligonucleotides that include a promoter for an RNA polymerase are all modified to prevent the initiation of DNA synthesis therefrom.

摘要： Disclosed are methods for selective amplification of target nucleic acid sequence using a tagged oligonucleotide comprising a target hybridizing sequence that hybridizes to a 3′-end of the target nucleic acid and a tag sequence situated 5′ to the target hybridizing sequence. The tagged oligonucleotide is hybridized to the target nucleic acid and, after reducing the effective concentration of unhybridized tagged oligonucleotide having an active form, a primer extension reaction is initiated to produce a primer extension product. Further amplification also utilizes a first oligonucleotide that hybridizes to the 3′ end of the complement of the target nucleic acid and a second oligonucleotide that hybridizes to the complement of the tag sequence. Also disclosed are reaction mixtures for use in the disclosed methods comprising the tagged oligonucleotide hybridized to target nucleic and substantially free of an active form of unhybridized tagged oligonucleotide.

摘要： Novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic are disclosed (i.e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, methods of nucleic acid amplification are disclosed which are robust and efficient, while reducing the appearance of side-products. In general, the methods use priming oligonucleotides that target only one sense of a target nucleic acid, a promoter oligonucleotide modified to prevent polymerase extension from its 3′-terminus and, optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or substantially eliminating the formation of side-pro ducts. The disclosed methods minimizes or substantially eliminate the emergence of side-products, thus providing a high level of specificity. Furthermore, the appearance of side-products can complicate the analysis of the amplification reaction by various molecular detection techniques. The disclosed methods minimize or substantially eliminate this problem, thus providing enhanced levels of sensitivity.
