  • Uncharged polynucleotide-binding polymers
    Patent number: 5470974
    Abstract: A composition of polymer molecules effective to bind, with substantially uniform binding affinity, to a single-stranded polynucleotide containing a target sequence of bases. The polymer molecules are composed of a sequence of base-pairing moieties effective to hydrogen bond to corresponding, complementary bases in the target sequence, under selected binding conditions, and a predominantly uncharged, achiral backbone supporting the base-pairing moieties at positions and in orientations which allow hydrogen bonding between the pairing moieties of the polymer and the corresponding complementary bases in the target sequence. The composition has diagnostic uses, in a solid-support assay system, and therapeutic uses involving inhibition or inactivation of target polynucleotides.
    Type: Grant
    Filed: February 25, 1994
    Date of Patent: November 28, 1995
    Assignee: Neu-Gene Development Group
    Inventors: James Summerton, Dwight Weller, Eugene Stirchak
