  • Patent number: 6783932
    Abstract: The stability of a triplex in solution is enhanced by adding to the solution, either before or after formation of the triplex, an effective amount of either of the following: (a) a water structure-making substance, at an appropriately high concentration, other than an alkali or alkaline earth metal cation, a tetramethylammonium cation, or a polyamine; or (b) a combination of said water structure-making substance and an alkali or alkaline earth cation or a tetramethylammonium cation or a polyamine.
    Type: Grant
    Filed: July 2, 1999
    Date of Patent: August 31, 2004
    Assignee: Princeton University
    Inventors: Jacques R. Fresco, John Laurence Richard Lavelle
  • Patent number: 6461810
    Abstract: Disclosed are methods for detecting in situ the presence of a target sequence in a substantially double-stranded nucleic acid segment, which comprises: a) contacting in situ under conditions suitable for hybridization a substantially double-stranded nucleic acid segment with a detectable third strand, said third strand being capable of hybridizing to at least a portion of the target sequence to form a triple-stranded structure, if said target sequence is present; and b) detecting whether hybridization between the third strand and the target sequence has occured.

  • Patent number: 5928863
    Abstract: A triple-stranded nucleic acid having a first nucleic acid strand that has a region of adjacent purine nucleoside residues; a second nucleic acid strand, at least a portion of which is hydrogen bonded in a Watson-Crick manner to the region of adjacent purine nucleoside residues of the first strand; and a third nucleic acid strand, at least a portion of which is hydrogen bonded to the portion of the region of adjacent purine nucleoside residues of the first strand, the portion of the region of adjacent purine nucleoside residues to which both the second strand and the third strand are bonded defining the triple-stranded nucleic acid.
