METHOD FOR OBTAINING OLIGONUCLEOTIDE

摘要

The present invention is to provide a method for obtaining an oligonucleotide such as RNA aptamer having high binding capacity to a target substance with easy-to-use and high purity. The method for obtaining oligonucleotide according to the present invention is as follows: A method for obtaining oligonucleotide comprising the steps of;
performing an electrophoresis of a nucleic acid molecule/target substance complex comprising a nucleic acid molecule and a target substance;
recovering said nucleic acid molecule/target substance complex;
extracting the nucleic acid molecule from said nucleic acid molecule/target substance complex;
gene amplifying said nucleic acid molecule.
