Title:
METHOD FOR DETECTING MUTATION AND KIT USED IN THE SAME
Document Type and Number:
Japanese Patent JP2012040029
Kind Code:
A
Abstract:

To provide a method for detecting a mutation that uses Tm analysis and is excellent in detection sensitivity.

A detection probe consisting of a polynucleotide complementary to a target sequence to be detected containing a detection site that has been mutated, and an inhibitory polynucleotide complementary to the non-target 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 by the DNA. Then while the hybrid product between the DNA and the detection probe is heated, a signal variation associated with rise in temperature is measured, then the signal variation is analyzed, and thereby a Tm value is determined, so that the presence of the mutation is determined.
