  • Patent number: 5698685
    Abstract: A method of generating a compound capable of interacting specifically with a selected macromolecular ligand is disclosed. The method involves contacting the ligand with a combinatorial library of oligomers composed of morpholino subunits with a variety of nucleobase and non-nucleobase side chains. Oligomer molecules that bind specifically to the receptor are isolated and their sequence of base moieties is determined. Also disclosed is a combinatorial library of oligomers useful in the method and novel morpholino-subunit polymer compositions.

  • Patent number: 5521063
    Abstract: 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.
