    摘要: The present invention concerns oligonucleotides containing one or more modified nucleotides which increase the binding affinity of the oligonucleotides to target nucleic acids having a complementary nucleotide base sequence. These modified oligonucleotides hybridize to the target sequence at a faster rate than unmodified oligonucleotides having an identical nucleotide base sequence. Such modified oligonucleotides include oligonucleotides containing at least one 2′-O-methylribofuranosyl moiety joined to a nitrogenous base. Oligonucleotides can be modified in accordance with the present invention to preferentially bind RNA targets. The present invention also concerns methods of using these modified oligonucleotides and kits containing the same.

    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.

    摘要: Compositions are described for detecting binding of an analyte to a binding partner attached to a nucleic acid hybridization switch probe that includes first and second arm sequences and a support sequence that is at least partially complementary to both arm sequences, allowing the probe under hybridization conditions to form a first conformation in the absence of the analyte and to form a second conformation in the presence of the analyte, and a label associated with the probe that produces a signal that indicates the conformation of the probe. Methods are described for detecting an analyte that forms a specific binding pair with the binding partner attached to the hybridization switch probe, thereby changing the probe from a first to a second conformation that results in a detectable signal that indicates the presence of the analyte in the sample.
