    • A probe for detecting a mutation in the JAK2 gene is provided that can detect a target sequence containing a mutation even when the target sequence containing the mutation and a non-target sequence containing no mutation coexist, which are different only in a single base from each other. The probe to be used is an oligonucleotide that is at least one oligonucleotide having a sequence identical to that of a region extending from a cytosine base (C) at position 84 to be considered as the first base to any one of the 17th to 22nd bases in the direction toward the 5′ end in exon 12 of the JAK2 gene consisting of the base sequence of SEQ ID NO: 1, with the cytosine base (C) being the 3′ end. Even in the case of a sample containing both the JAK2 genes with a mutation that has occurred and without a mutation that has occurred, the use of such a probe in, for example, Tm analysis allows the former mutation to be detected. Preferably, the probe is labeled with a fluorescent dye.

    • A method of detecting a mutation is provided that uses Tm analysis and is excellent in detection sensitivity. A detection probe consisting of a polynucleotide complementary to a sequence to be detected containing a detection site that has been mutated and an inhibitory polynucleotide complementary to a sequence not to be detected containing the detection site that is unmutated are added to a sample containing a DNA to be detected in which the detection site has been mutated and a DNA not to be detected in which the detection site is unmutated, so that the detection probe is hybridized with the DNA. Then while the hybridization product between the DNA and the detection probe is heated, a signal variation associated with an increase in temperature is measured, then the signal variation is analyzed, and thereby a Tm value is determined, based on which the presence of the mutation is determined.

    • The present invention provides a control detection method for easily detecting a positive control and a negative control simultaneously in one reaction system. An amplification reaction is carried out by adding a control template nucleic acid to a reaction system for detecting controls. The template nucleic acid can be amplified by a primer capable of amplifying an objective target sequence. An amplification region of the control template nucleic acid amplified by the primer can be hybridized with a detection probe capable of hybridizing to the target sequence. A Tm value (TmC) of a double-stranded nucleic acid composed of the amplification region of the control template nucleic acid amplified by the primer and the detection probe is set different from a Tm value (TmA) of a double-stranded nucleic acid composed of the target sequence and the detection probe. Thereby, it can be determined whether or not amplification occurs in a reaction system on the basis of the presence or absence of a peak at the TmC and it can be determined whether or not a reaction system is contaminated with undesired nucleic acid on the basis of the presence or absence of a peak at a temperature other than TmC.
    • 本发明提供一种用于在一个反应​​系统中同时容易地检测阳性对照和阴性对照的控制检测方法。 通过将对照模板核酸加入到用于检测对照的反应系统中进行扩增反应。 模板核酸可以通过能够扩增目的靶序列的引物扩增。 由引物扩增的对照模板核酸的扩增区可以与能够与靶序列杂交的检测探针杂交。 将由引物扩增的对照模板核酸的扩增区和检测用探针构成的双链核酸的Tm值(TmC)设定为与构成的双链核酸的Tm值(TmA)不同 的目标序列和检测探针。 因此,可以基于在TmC的峰的存在或不存在来确定反应体系中是否发生扩增,并且可以基于以下方式确定反应体系是否被不期望的核酸污染 在TmC以外的温度下存在或不存在峰。
