  • Patent number: 9562258
    Abstract: A method for detecting the presence of a target nucleotide sequence in a sample of DNA is described herein in which a test sample comprising single stranded DNA is exposed to a DNA probe and a nicking endonuclease under conditions that would permit sequence-specific hybridization of the probe to a complementary target sequence. The probe comprises a sequence complementary to the target sequence to be detected and this sequence also includes a recognition sequence for the nicking endonuclease. If the sample contains the target sequence, the probe hybridizes to the target and is cleaved by the nicking endonuclease, which leaves the target intact. Observing the presence of probe cleaved by the nicking endonuclease indicates the presence of the target nucleotide sequence in the sample of DNA.
