    摘要: A method for detecting a gene mutation(s), the method comprising the steps of: hybridizing a single-stranded circular DNA and a primer with a target polynucleotide containing a first region and a second region adjacent to the 3′-side of the first region and containing a mutation; performing a nucleic acid amplification reaction by rolling circle amplification based on formation of a complex of the target polynucleotide, the primer, and the single-stranded circular DNA; and detecting amplified nucleic acid with a detection reagent. In this method, the single-stranded circular DNA contains a sequence complementary to the first region of the target polynucleotide, a primer-binding sequence adjacent to the 5′-side thereof, and preferably a sequence complementary to a detection reagent-binding sequence. The oligonucleotide primer contains a region having a sequence complementary to the second region of the target polynucleotide, and a region adjacent to the 3′-side thereof and having a sequence complementary to the primer-binding sequence of the single-stranded circular DNA.

    摘要: An RNA detection kit comprising: (i) a single-stranded circular DNA template containing: a sequence of 10 to 30 bases complementary to a first portion of a target RNA; a primer-binding sequence of 7 to 8 bases adjacent to 5′-side thereof; and a sequence complementary to a detection reagent-binding sequence such as a guanine quadruplex-forming sequence; (ii) an oligonucleotide primer containing: a sequence of 8 to 15 bases complementary to a second portion adjacent to the 3′-side of the first portion of the target RNA; and a sequence of 7 to 8 bases adjacent to 3′-side thereof and complementary to the primer-binding sequence of the single-stranded circular DNA template; and (iii) a detection reagent such as a guanine quadruplex-binding reagent; is provided.
