Drug Information

MeSH：

Chemicals that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags. (See all compounds classified as Fluorescent Dyes.)

MeSH Entry Terms：

diamidino compound 253-50
