Fluorescein (FITC) 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 isothiocyanate (FITC) is a derivative of fluorescein used in wide-ranging applications [1] [2] including flow cytometry. First described in 1942, [3] FITC is the original fluorescein molecule functionalized with an isothiocyanate reactive group (−N=C=S), replacing a hydrogen atom on the bottom ring of the

FITC is one of the most widely used dyes for fluorescent applications, therefore most instruments come standard with a 488 nm laser and FITC filter set up. FITC is commonly conjugated to secondary antibodies and used in applications such as flow cytometry, immunocytochemistry, and immunohistochemistry.

FITC (fluorescein isothiocyanate) is widely used to label proteins, antibodies, peptides, hormones, amine-modified oligonucleotides, and other amine-containing molecules with the green fluorescent dye fluorescein. The isothiocyanate moiety (-N=C=S) on FITC reacts with amino-terminal and primary amine groups on the target biomolecule to form a ...

In immuno histology/ cytology, Fluorescein-5-isothiocyanate (FITC) for biochemistry and for fluorescence microscopy, serve as marker substance for the visualization and for the detection of tissue-bound bio molecules like e.g. antigens, lectins, various proteins, peptides, nucleic acids, oligo- and polysaccharides in samples of human origin.

Fluorescein 5(6)-isothiocyanate, also known as FITC, is a weakly acidic hydroxyxanthene whose overall size is small, with both carboxylic acid and isothiocyanate substituents on the pendant phenyl ring. The dye has a moderately sized, nonplanar aromatic system.

2022年3月17日 · First termed in 1942 by A.H. Coons, FITC is a unique fluorescein molecule having an isothiocyanate reactive group (-N=C=S), which replaced the hydrogen atom located at the base of its structure. In this article, we’ll discuss FITC labeling techniques and provide tips and tricks for maximizing yield.

Fluorescein isothiocyanate (FITC) is one of the most widely used fluorescein derivatives. It has the typical properties of fluorescein derivatives, being prone to degradation in water and unsuitable for long-term storage. Among its forms, 5-FITC is used more often than 6-FITC.

Key information: FITC (an amine-reactive version of the parent dye, fluorescein) is a widely-used green fluorescent dye supplied with an isothiocyanate reactive group for the labeling of primary amines. FITC is bright and has good water-solubility, however it is sensitive to changes in pH and temperature, and has a relatively high ...

FITC, also known as fluorescein 5-isothiocyanate, is a fluorescein derivative used in a variety of applications including flow cytometry. FITC reacts with amine groups to form conjugates with proteins for detection by various fluorescent-based applications.
