:Fluorescein 5-isothiocyanate
Description:
Fluorescein 5-isothiocyanate (FITC) is a fluorescent dye commonly used in biological research and immunology for labeling proteins, antibodies, and nucleic acids. It is characterized by its bright green fluorescence when excited by ultraviolet or blue light, making it an excellent marker for fluorescence microscopy and flow cytometry. The compound features a fluorescein backbone, which contributes to its strong fluorescence properties, and an isothiocyanate functional group that facilitates covalent bonding to amino groups in proteins. FITC is soluble in organic solvents and water, allowing for versatile applications in various experimental conditions. Its reactivity with primary amines enables the formation of stable conjugates, which are crucial for tracking biomolecules in live cells or tissues. However, it is important to handle FITC with care, as it can be sensitive to pH changes and light exposure, which may affect its fluorescence intensity. Overall, FITC is a valuable tool in the field of biochemistry and molecular biology for visualizing and studying cellular processes.

CAS:Fluorescent labeling reagent for proteins. FITC-conjugated antibodies are commonly used in immunohistochemistry for immunofluorescent staining. Fluorescein isothiocyanate (FITC) is a yellow-green colored low molecular weight dye which couples to proteins via reaction with primary amine groups at high pH. FITC is excitable at 488nm, close to its absorption maximum at 494nm, and produces maximum fluorescence emission around 520nm. It is commonly conjugated with antibodies for use in indirect immunofluorescence.Formula:C21H11NO5SPurity:Min. 90.0 Area-%Molecular weight:389.39 g/molFITC
