Fluorescein dye

Fluorescein isothiocyanate (FITC) is an organic fluorescent dye and probably one of the most commonly used in immunofluorescence and flow cytometry. It has an excitation/emission peak at 495/517 nm and can be coupled to distinct antibodies with the help of its reactive isothiocyanate group, which is binding to amino, sulfhydryl, imidazoyl, tyrosyl or carbonyl groups on proteins 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)

Fluorescent dyes, also known as reactive dyes or fluorophores, have been used by biologists for decades. Fluorescent dyes offer higher photostability and brightness compared to fluorescent proteins and do not require a maturation time. However, fluorescent dyes are usually targeted to proteins of interest by antibody conjugates or peptide tags Fluorescein is a fluorescent dye that is used as a diagnostic aid. The unbound fraction of the drug responds to electromagnetic radiation and light between the wavelengths of 465—490 nm and emits light at wavelengths of 520—530 nm. Thus, the fluorescein hydrocarbon is excited by blue light and emits yellowish-green light Fluorescein derivatives are the most common fluorescent reagents for biological research because of their high absorptivity, excellent fluorescence quantum yield, and good water solubility. Fluorescein-based dyes and their conjugates have several performance characteristics that may facilitate or limit use in certain applications Fluorescein can be used as a reference standard for ether, ester and phosphate substrates derived from this green-fluorescent dye.
