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

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.

FITC is a fluorescein derivative consisting of a fluorescein core and an amine-reactive isothiocyanate moiety. The isothiocyanate group reacts with primary amines forming covalent thiourea bonds that attach fluorescein to the biomolecule.

FITC，英文全称 Fluorescein Isothiocyanate，中文名称异硫氰酸荧光素，是生物学中应用最为广泛的一种绿色荧光素衍生物。 FITC 具有高吸收率和优良的荧光量子产率等特点。 FITC 的异硫氰酸基团可与蛋白质上的氨基、巯基、咪唑、酪氨酰、羰基等基团相结合，从而实现包括抗体，凝集素在内的蛋白标记。 FITC 除了用作蛋白质标记物，还可用作蛋白质荧光示踪剂，通过标记抗体 …

Fluorescein isothiocyanate (FITC) is a fluorescent probe that is commonly used in the preparation of conjugates with biological molecules. It has high water solubility, bright fluorescence, and low nonspecific binding with biological tissues.

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-5-isothiocyanate) is a fluorescent compound with an excitation peak at 491 nm and an emission peak at 516 nm. Other spectra of interest include: Cy5 (Cyanine-5), iFluor 488, and CFSE (fluorescein, CFDA, SE).

FITC (Fluorescein Isothiocyanate), is one of the green fluorescein derivatives widely used in biology. FITC has the characteristics of high absorptivity and excellent fluorescence quantum yield.

Mar 17, 2022 · 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 a fluorescein derivative, it can be used as a fluorescent probe in flow cytometry and fluorescence microscopy.
