GENE ANALYSIS METHOD, AND DEVICE AND KIT FOR ANALYSIS OF GENE

摘要

A DNA sequencer is a device for analyzing a nucleotide sequence, and is not intended for the detection of a polymorphism that occurs in a trace amount. Furthermore, the crosstalk at the wavelength of a fluorescent substance to be used for the labeling of DNA interferes with the acquisition of low signals on a single coordinate. Therefore, it has been difficult to detect the mutation of a gene having a small abundance ratio, such as the mutation in a somatic cell. A gene analysis device is equipped with: multiple flow paths which respectively correspond to nucleotide species in a nucleic acid sample in which the nucleotides are labeled separately; a wave form data generation section for detecting a label signal from each of the nucleotides in the nucleic acid sample that is placed in each of the multiple flow paths, thereby generating wave form data on the intensity of the detected signal; a peak detection section for detecting a peak value of the wave form data for each of the nucleotides; and a data integration section for carrying out an integration processing of multiple sets of wave form data.
