NUCLEIC ACID ANALYSIS DEVICE, NUCLEIC ACID ANALYZER, AND METHOD FOR ANALYZING NUCLEIC ACIDS

摘要

In a nucleic acid analysis device that excites a fluorescent dye on a nucleic acid sample affixed to the surface of a substrate using evanescent light and carries out detection, detection of the fluorescence signal is achieved with a high SN ratio even for long nucleic acid samples. This nucleic acid analysis device has a plurality of areas for affixing nucleic acid samples to the surface of the supporting base, and a single molecule nucleic acid sample is affixed to at least one of these areas. In the nucleic acid analysis device, which carries out an extension reaction on the affixed nucleic acid sample to determine the sequence, the affixing of the single nucleic acid sample molecule on the support substrate is at two or more points.
