일반 설명

Fluorescein (free acid, CI 45350) is a xanthene dye. Fluorescein (free acid) molecule can be divided into two parts. One part contains xanthene moiety which acts as fluorophore and the other part of the molecule bears benzene moiety which is the fluorescence-controlling moiety.

애플리케이션

Fluorescein (free acid) has been used as a staining agent in retinal imaging.
Fluorescein (free acid) is widely used as a fluorescent stain and trace for many living cells and tissue applications. It is also suitable as a marker for the study of motility of bile canaliculi. Some of the clinical applications are evaluating the ocular surface and delineation of brain regions lacking a blood-brain barrier to permit accurate surgical resection of malignant glioma. Fluorescein angiography helps investigate changes in retinal blood supply. Fluorescein also plays a role as a physiological tracer to characterize the salmon′s intestinal permeability (Schep et al., 1998), and for the fluorophotometric measurement of aqueous humor flow. It is widely employed as a quantum yield standard.

Rational design strategies based on practical fluorescence modulation mechanisms would enable us to rapidly develop novel fluorescence probes for target molecules. Here, we present a practical and general principle for modulating the fluorescence properties of fluorescein. We hypothesized that (a)
