fluorescein
A green dye that fluoresces bright yellow in blue or ultraviolet light. It is used to tag (label) and thus show up ANTIBODIES in tissues. It is also much used by eye specialists (ophthalmologists) to show up ulcers on the cornea and to delineate for photography the blood vessels of the retina. For the latter purpose, the due is injected rapidly into the bloodstream (fluorescein angiography). The drug is on the WHO official list. Brand names are fluorescein, Minims fluorescein, Minims lignocaine (lidocaine, a local anaesthetic) and fluorescein, and Minims proxymetacaine (a local anaesthetic) and fluorescein.Fluorescein
