일반 설명
Fluorescein dye is the most commonly used fluorescent probe.[1] It is used to stain epithelial defects and analyse the integrity of corneal epithelium. Fluorescein is used in the diagnosis of corneal perforation.[2] Oral or intravenous fluorescein is used in fluorescein angiography to detect diabetic retinopathy and choroidal neovascular membrane.[3]
애플리케이션
Fluorescein has been used:
- in the permeability assay of Caco-2 cells[4][5]
- to test its suitability to serve as lifetime fluorescence standards[6]
- as a fluorophore for the fast recovery of fluorescence peaks and fluorophore concentration in the presence of hemoglobin[7]
- as a fluorescent probe in oxygen radical absorbance capacity (ORAC) assay[8]
