Nucleotide sequence determination method, nucleotide sequence determination system and nucleotide sequence determination program

摘要

A method for determining nucleotide sequence encompasses (a) injecting a solution containing a sample nucleic acid into a chip cartridge, (b) detecting first detection, second detection, and control signals through electrodes on the chip cartridge, (c) calculating a first difference between a mean value of the control signals and a mean value of the first detection signals, and dividing the first difference by the mean value of the control signals to define X, (c) calculating a second difference between the mean value of the control signals and a mean value of the second detection signals, and dividing the second difference by the mean value of the control signals to define Y, (d) calculating an angle between a positive X-axis and a vector from origin to a point (X, Y), and (d) comparing the angle with angle judgment criteria so as to identify a genotype of the sample nucleic acid.
