DETAILS

Description (English)
Application
The two isomers are produced by the usual synthesis. Most publications imply they are interchangeable when used for the preparation of the isothiocyanate for fluorescent antibody work. In fact, most commercial preparations are not even labeled as to whether or not they are mixtures.
Other Notes
All known glycosaminoglycuronans react with this fluorescein derivative to yield fluorescent derivatives1
Note: Do not confuse with fluorescamine.
