FLUORESCENT INDICATOR USING FRET

摘要

It is intended to provide a fluorescent indicator based on homo-FRET (fluorescence resonance energy transfer) with the use of a fluorescent molecule having a small Stoke's shift to thereby develop a system of visualizing molecular interaction. Namely, a fluorescent indicator wherein fluorescent molecule components having substantially the same fluorescent characteristics are attached to the N-terminal side and the C-terminal side of a target sequence to which a substance to be analyzed binds or acts to thereby alter the stereostructure of the indicator.
