Method for detecting oligonucleotides and determining base sequence of nucleic acids

摘要

Disclosed are a method which can simultaneously analyze a plurality of analytes and can realize the determination of the base sequence of a large quantity of gene information in a short time, and an apparatus for the method. The method comprises the steps of: preparing four samples, for each of a plurality of nucleic acid analytes, containing analyte nucleic acid-derived oligonucleotide fragments with the end bases having been base-specifically fragmented; labeling the oligonucleotide fragments with a different label for each of the analyte nucleic acids; and subjecting the four samples to an analytical method which can distinguish oligonucleotide fragments based on a difference in length of one base, thereby determining the base sequence of the target nucleic acids.
