METHOD OF ELECTROCHEMICALLY DETECTING NUCLEIC ACID WITH THE USE OF DNA CONJUGATE

摘要

Provided is a technique of conveniently and accurately detecting a gene without resorting to DNA immobilization and so on. A modified oligonucleotide having a host compound such as cyclodextrin attached to one end thereof and containing a base sequence that is complementary to such an extent as being hybridizable specifically with the base sequence at a desired site of a target polynucleotide.
