제목 Studies of photo-reversible fluorescent hydrogel with pdDronpa: Synthesis and characterization
초록 Dronpa145N is a tetrameric fluorescent protein undergoes reversible photo-switching and photo-dissociation by cyan light (dissociation) and violet light (re-association). pdDronpa is a dimeric derivative of Dronpa145N which is bright and more sensitive to light while forms less aggregates both in vitro and in vivo. We synthesized light-controllable fluorescent hydrogel with polyethyleneglycol (PEG)-maleimide and pdDronpa. This hydrogel showed reversible gel-sol transition under cyan light and violet light. Then, we added restriction enzyme-treated lambda DNA fragments during hydrogel synthesis. After cyan light illumination, DNA fragments were able to escape from the hydrogel, and DNA chelating dye could bind to them resulting in strong red fluorescence.
