  • Patent number: 9909168
    Abstract: The present invention relates to an oligonucleotide having a novel structure and a method of synthesizing nucleic acid by using the same as a primer. This oligonucleotide is provided at the 5?-side of the primer with a nucleotide sequence substantially the same as a region synthesized with this primer as the origin of synthesis. The present invention realizes synthesis of nucleic acid based on an isothermal reaction with a simple constitution of reagents. Further, the present invention provides a method of synthesizing highly specific nucleic acid on the basis of this method of synthesizing nucleic acid.

  • Patent number: 5849487
    Abstract: The present invention relates to a method of detecting a polynucleotide, comprising hybridizing a polynucleotide of known nucleotide sequence with a nuclease-resistant oligonucleotide primer having a sequence complementary to a part of the polynucleotide, then adding at least one kind of deoxynucleoside triphosphate, DNA polymerase and nuclease thereto, synthesizing a complementary strand being a nucleotide species located adjacent to the 3'-terminal of the primer and complementary to the polynucleotide, followed by decomposition thereof, the synthesis and decomposition of the complementary strand being repeated one or more times, and detecting the resulting pyrophosphoric acid or deoxynucleoside monophosphate. The present invention also includes a detection kit used for this method of detecting a polynucleotide.
