Extending applicability of the oxygen radical absorbance capacity (ORAC-fluorescein) assay.
Journal of Agricultural and Food Chemistry, 2004The ORAC-fluorescein (ORAC-FL) method recently validated using automatic liquid handling systems has now been adapted to manual handling and using a conventional fluorescence microplate reader. As calculated for Trolox, the precision of the method was

Advances in modifying fluorescein and rhodamine fluorophores as fluorescent chemosensors.
Chemical Communications, 2013The fluorophores based on xanthene scaffolds, mainly containing rhodamine and fluorescein dyes, have attracted considerable interest from chemists due to their excellent photophysical properties such as high absorption coefficient, high fluorescence ...

The Use of Fluorescein in Vitrectomy
Archives of Ophthalmology, 1987To the Editor. —Fluorescein has been proposed as an aid in vitreous surgery. This agent can be injected intravenously prior to operation 1 or introduced directly into the eye. 2 Intravenous injection carries the risk of serious systemic reaction and is also of little use in unplanned procedures, since the dye has to be injected at least 18 hours ...

Photoallergic reaction to fluorescein
Contact Dermatitis, 1990A photoallergie reaction to fluorescein was demonstrated in a male diabetic by photopatch and photoprovocation tests. Sensitization was acquired by tonometries using a fluorescein‐containing local anesthetic, preceding fluorescein angiography for diagnosis of diabetic retinopathy. Histopathological examination of skin lesions induced in both photopatch

Fluorescein dynamics in the eye
Documenta Ophthalmologica, 1969Fluorescein injected into the vitreous body is transported rapidly out of the eye in the posterior segment. Injected in excess or in the presence of competitive inhibitors it leaves more slowly, by way of the anterior chamber. Systemically administered fluorescein reaches higher levels in the anterior chamber when inhibitors are acting on the eye ...
