  • Patent number: 5723288
    Abstract: Disclosed is a method of fluorescent detection of a nucleic acid. The method comprises contacting to the nucleic acid a bis-dicationic aryl furan compound, such as 2,5-bis?4-(4,5,6,7-tetrahydro-1H-1,3-diazepin-2-yl) phenyl! furan; 2,5-bis{?4-(N-isopropyl) amidino! phenyl}furan; and physiologically acceptable salts thereof, and exposing the nucleic acid to light at a frequency to induce fluorescence of the compound. A method for fluorescent detection of cytoskeleton elements, and novel bis-dicationic aryl furan compounds are also disclosed.
    Type: Grant
    Filed: May 6, 1994
    Date of Patent: March 3, 1998
    Assignees: The University of North Carolina at Chapel Hill, Georgia State University Research Foundation, Inc.
