  • Detecting reagent for double-stranded nucleic acid and double-stranded nucleic acid detecting method
    Patent number: 6528648
    Abstract: The present invention provides a novel detecting reagent for double-stranded nucleic acid, and a method of using it to detect double-stranded nucleic acid formed by hybridization with a probe, with absolutely no labeling of the target nucleic acid. The detecting reagent for double-stranded nucleic acid of the invention is characterized by comprising, in the same molecule, a naphthalenediimide group which is intercalatable into double-stranded nucleic acid and a &bgr;-diketone group capable of forming a lanthanoid metal complex.
