Outline of Final Research Achievements

This research aims to develop a oligonucleotide aptamer containing a fluorescent artificial nucleoside That has a luminescent function to Aequorea victoria. Aequorea victoria emits to produce a fluorescent protein complex composed of green fluorescent protein and aequorin. In this investigation, a natural nucleobase cytosine is converted to p-hydroxybenzylideneimidazolinone which is the luminescent body of green fluorescent protein, and sarched for oligonucleotide sequences which recognizes coelenterazine like aequorin. The synthesis of luminescent material was completed, but the aptamer sequences with high recognizing ability was not completed, and it is necessary to continue the research.
