CAS:Applications A fluorescent tracer used for many applications. It is used in ophthalmology as a tool in the diagnosis of corneal abrasions, corneal ulcers and herpetic corneal infections. It can attach to certain biologically active molecules, thus allowing biologists to target the fluorophore to specific proteins or structures within cells. Dyes and metabolites.

CAS:Fluorescein is used as a fluorescent tracer for many applications including in a type of dye laser as the gain medium, in forensics and serology to detect latent blood stains and in dye tracing. It is used to localise multiple muscular ventricular septal defects during open heart surgery and confirm the presence of any residual defects. It is applied to teeth to reveal plaque.

CAS:Fluorescein is a fluorescent molecule often used in in vitro assays, immunohistochemistry, microscopy, and clinical analytics. Fluorescein is not a natural product and was first synthesized in 1871 by Adolf von Baeyer, a later Nobel-prize winner for his work on organic dyes. Fluorescein has an absorption maximum of 494 nm and an emission maximum of 512 nm; these values can however slightly change depending on the solution medium. Fluorescein is used clinically in ophthalmology to assess the blood flow in the eye blood vessels and to detect eye injuries such as foreign bodies and possible abrasions. Interestingly, fluorescein has been found to possess peroxidase activity under certain conditions.Formula:C20H12O5Color and Shape:PowderMolecular weight:332.31 g/molFluorescein
