    摘要: A method for determining the presence or absence of a mutation on the basis of the presence or absence of amplification with high reliability is provided. A target sequence including a target site contained in a sample nucleic acid is amplified using a primer that can hybridize to a region including the target site contained in the sample nucleic acid in the presence of a novel MutS having an amino acid sequence of SEQ ID NO: 2, and then the presence or absence of a mutation at the target site is determined on the basis of the presence or absence of amplification. The novel MutS binds more specifically to a mismatched base pair than to a fully-matched base pair, whereby an extension reaction caused by a mismatch-binding primer is suppressed. Thus, according to the present invention, the presence or absence of a mutation can be determined with high reliability.

    摘要: The present invention is to provide a pretreatment method that allows RNA to be detected promptly and simply. RNA degradation activity due to lactoferrin present in the human rhinal mucosa is inhibited, for example, by adding iron ion and carbonate ion to a biological sample that contains the human rhinal mucosa. With the pretreated biological sample, an RNA virus gene can be amplified by a reverse transcriptase. Iron ion and carbonate ion can also inhibit reverse transcriptase inhibition due to lysozyme C contained in the human rhinal mucosa. Further, it is preferable to remove the envelope of the RNA virus by adding SDS to the biological sample that contains the human rhinal mucosa.

    摘要: The present invention provides a primer set including primers that can be designed easily, with which an amplification distance can be shortened. Provided is a primer set for use in a method for isothermally amplifying a target nucleic acid sequence 4. The primer set includes a first primer 1F and a second primer 1R. The first primer 1F includes, on the 3′ side thereof, a sequence (A′) that can hybridize to a sequence (A) on the 3′ side of the target nucleic acid sequence. The second primer 1R includes, on the 3′ side thereof, a sequence (B′) that can hybridize to a sequence (B) on the 3′ side of either a strand extended from the first primer or a complementary strand of the target nucleic acid sequence 4. The first primer 1F and the second primer 1R include, on the 5′ sides thereof, sequences (C) that are substantially identical to each other.
