  • Catalytic nucleic acid and methods of use
    Patent number: 6387617
    Abstract: A nucleic acid molecule is provided which is initially catalytically inactive but which can complex with a specific co-factor, e.g., a nucleic acid molecule or a non-nucleic acid molecule, to form a catalytically active nucleic acid molecule. The catalytically active nucleic acid molecule can be used to detect the presence of a non-nucleic acid co-factor or of a nucleic acid co-factor using the nucleic acid sequence of the present invention.
    Type: Grant

  • Detection of biomolecules
    Patent number: 6214546
    Abstract: The present invention concerns a method for detecting the presence of a catalytically active ribozyme in a medium. The detection of the catalytically active ribozyme may be a goal by itself, or the ribozyme may serve as a reporter for the presence of other biomolecules in an assayed sample. The detection is carried out in a catalytic system wherein the presence of the active ribozyme serves to produce other active ribozymes in a positive-feedback amplificatory manner.
