LABELED NUCLEIC ACID AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To use a β-diketone europium complex for detecting a nucleic acid in a region at a low concentration which cannot be detected with a conventional fluorescent dye in a DNA chip or a DNA microarray and to provide a method for assaying an immobilized DNA immobilized on a stationary phase such as a glass or a membrane. SOLUTION: A labeling substance represented by the general formula (I) is bound through a specific connecting group to the nucleic to provide a labeled nucleic acid.
