Drug Information
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.)
5 Isothiocyanatofluorescein
Fluorescein 5-isothiocyanate Use and Manufacturing
Fluorescein -5-isothiocyanate is a kind of fluorescent marker for biochemical applications. Reacts under mild conditions with primary amines and it is also used in modification of actin at lys-61, labelling of FAB and the modification of thiol groups. Fluorescent labeling reagent for proteins. Used in the fluorescent antibody technique for rapid identification of pathogens
