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)-N3 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.
本发明的目的是提供一种用于基因分析的开关型荧光化合物(产生荧光的分子系统),它具有高稳定性(即长期保持活性)和高灵敏度,可以放大微量的基因信号并对其进行观察。本发明提供了一种非荧光分子,该分子具有荧光物质骨架,如荧光素骨架,并具有由-O-C(Y1)(Y2)-N3代表的基团,其中Y1和Y2各自代表氢原子、含1至6个碳原子的烷基、含1至6个碳原子的烷氧基、含6至10个碳原子的芳基或氰基。
