A new photocaged fluorescent compound, azidomethyl fluorescein, was successfully utilized to monitor the dynamics of oligonucleotides in living human cells.
It is an object of the present invention to provide an on-off type fluorescent compound (a fluorescence-producing molecule system) used in gene analyses, which is highly stable (namely, being active for a long period of time) and highly sensitive, and which enables amplification of a trace amount of gene signal and observation thereof. The present invention provides a nonfluorescent molecule having a fluorescent substance skeleton such as fluorescein skeleton and having a group represented by —O—C(Y1)(Y2)-N

wherein each of Y1 and Y2 represents a hydrogen atom, an alkyl group containing 1 to 6 carbon atoms, an alkoxy group containing 1 to 6 carbon atoms, an aryl group containing 6 to 10 carbon atoms, or a cyano group, in the molecule.
