    摘要： The invention relates to compositions and methods for rapidly detecting or isolating a target nucleic acid sequence in a polynucleotide-containing sample. The sample is exposed to a rapid pairing reagent, which contains a rapid capture component, effective to rapidly and non-selectively bind polynucleotides, and a target specific probe, effective to selectively bind the target nucleic acid sequence. Selectively disrupting the binding between the capture component and polynucleotides leaves only target sequence bound to the rapid pairing reagent.

    摘要： Polymeric compositions effective for delivering compounds in living organisms are described. The compositions include polypeptides which exhibit solubility in both hydrophilic and lipophilic environments by undergoing a reversible pH-dependent transition from a low-pH, lipophilic form to a high-pH, hydrophilic form.

    摘要： The present invention describes an assay system wherein target polynucleotide molecules are captured on a support by base-specific binding to support-bound polymers, which are themselves substantially uncharged, and the target polynucleotides can be detected on the basis of their backbone charge. The assay system may also include polycationic reporter molecules which are designed to bind to the fully charged analyte backbone, but not the uncharged (or substantially uncharged) polymer backbone. In one embodiment, the reporter molecules are composed of a polycationic moiety or tail designed to bind electrostatically to a fully charged polynucleotide, under conditions where the reporter does not bind to the less charged or uncharged binding polymer carried on the diagnostic reagent.

    摘要： Alpha-morpholino subunits and polymer compositions composed of alpha-morpholino subunits are disclosed. These subunits can be linked together by uncharged linkages, one to three atoms in length, joining the morpholino nitrogen of one subunit to the 5' exocyclic carbon of an adjacent subunit. Each subunit contains a purine or pyrimidine base-pairing moiety effective to bind by hydrogen bonding to a specific base or base-pair in a target polynucleotide. The polymers of the present invention can be used in place of standard RNA or DNA oligomers for a number of standard laboratory procedures, for example, as probes in solid-phase systems and nucleic acid hybridization analyses. Further, the polymers of the present invention have potential use as therapeutic agents in anti-sense-type technologies.

    摘要： The present invention describes a polymer composition effective to bind, in a sequence-specific manner to a target sequence of a duplex polynucleotide, at least two different-oriented Watson/Crick base-pairs at selected positions in the target sequence. The composition includes an uncharged backbone with 5- or 6-membered cyclic backbone structures and selected bases attached to the backbone structures effective to hydrogen bond specifically with different oriented base-pairs in the target sequence. Also disclosed are subunits useful for the construction of the polymer composition. The present invention further includes methods for (i) coupling a first free or polymer-terminal subunit, and (ii) isolating, from a liquid sample, a target duplex nucleic acid fragment having a selected sequence of base-pairs.
