Fluorescein is a fluorophore commonly used in microscopy, in a type of dye laser as the gain medium, in forensics and serology to detect latent blood stains, and in dye tracing. Fluorescein has an absorption maximum at 494 nm and emission maximum of 512 nm (in water). The major derivatives are … See more Fluorescein is an organic compound and dye based on the xanthene tricyclic structural motif, formally belonging to triarylmethine dyes family. It is available as a dark orange/red powder slightly soluble in water and … See more The fluorescence of this molecule is very intense; peak excitation occurs at 495 nm and peak emission at 520 nm. Values for the deprotonated form in basic solution. Fluorescein has a See more Approximately 250 tons/y were produced in the year 2000. The method involves the fusion of phthalic anhydride and resorcinol, similar to the route described by Adolf von Baeyer in 1871. In some cases, acids such as zinc chloride and methanesulfonic acid are employed to … See more Fluorescein sodium, the sodium salt of fluorescein, is used extensively as a diagnostic tool in the field of ophthalmology and See more Oral and intravenous use of fluorescein can cause adverse reactions, including nausea, vomiting, hives, acute hypotension, anaphylaxis and … See more Many derivatives of fluorescein are known. Examples are: • fluorescein isothiocyanate 1, often abbreviated as FITC, features an isothiocyanate group … See more • Chemical derivatives of fluorescein: • Fluorescein diacetate hydrolysis, a biochemistry laboratory test • Other dyes: • Precursor aromatic heterocyclic chromophore structures: See more WebJun 15, 2016 · In the primary care setting, a Wood lamp or ophthalmoscope with a cobalt filter is often used for fluorescein visualization.

Webfluorescein. A fluorescent, weak dibasic acid with a molecular weight of 376 whose sodium salt is used in dilute solution as a dye in the fitting of contact lenses, in the detection of … WebFluorescence intensity increases after the immediate reaction with hROS such as hydroxyl radical and peroxynitrite. Since HPF does not react with nitric oxide, superoxide and hydrogen peroxide, it can differentially detect peroxynitrite. HPF is resistant to light-induced autoxidation.

WebFluorescein angiography is a type of eye test used to diagnose retinal conditions. It can also be used as an early way to gauge whether someone might have complications with … WebFluorescein is an ocular stain used to show defects and abrasions in the corneal epithelium. The pooling of fluorescein on small corneal defects is best seen by means of ultraviolet or cobalt blue light for illumination. This causes the fluorescein to fluoresce. There is a danger with fluorescein in solution form. WebFluorescein is stimulated by blue light (465 to 490 nm) and emits at a green wavelength (520 to 530 nm). Fluorescein angiography requires the use of two filters, an exciter filter that transmits the blue light and a barrier filter that transmits the emitted green light.
