  • Patent number: 11035012
    Abstract: The invention provides chimeric capture probes immobilizable via an L-nucleic acid tail that can bind to a complementary L-nucleic acid in an immobilized probe. The capture probes are useful for capturing a target nucleic acid from a sample. The L-nucleic acid in the tail of the capture probe bind to the complementary L-nucleic acid in the immobilized probe with similar affinity as would otherwise equivalent D-nucleic acids. However, the L-nucleic acid of the capture probe tail and immobilized probes do not form stable duplexes with D-nucleic acids present in the in the sample containing the target nucleic acid. Binding of nucleic acids in the sample directly to immobilized probe or to the tail of the capture probe is reduced or eliminated increasing the sensitivity and/or specificity of the assay.

  • Patent number: 7399852
    Abstract: 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.

  • Publication number: 20060068417
    Abstract: Methods of the invention separate a target nucleic acid from a sample by using at least one capture probe oligonucleotide that contains a target-complementary region and a member of a specific binding pair that attaches the target nucleic acid to an immobilized probe on a capture support, thus forming a capture hybrid that is separated from other sample components before the target nucleic acid is released from the capture support and hybridized to a detection probe to form a detection hybrid that produces a detectable signal that indicates the presence of the target nucleic acid in the sample. Compositions for practicing the methods of the invention include a capture probe oligonucleotide made up a target-complementary region sequence and a covalently linked capture region sequence that includes a member of a specific binding pair.

  • Publication number: 20020028459
    Abstract: A method for capturing a target polynucleotide in a sample onto a solid support with an attached immobilized probe by using a capture probe and two different hybridization conditions, which preferably differ in temperature only, is disclosed. The two hybridization conditions control the order of hybridization, where the first hybridization conditions allow hybridization of the capture probe to the target polynucleotide, and the second hybridization conditions allow hybridization of the capture probe to the immobilized probe. The method may be used to detect the presence of a target polynucleotide in a sample by detecting the captured target polynucleotide or amplified target polynucleotide.
