CAS 27072-45-3: Fluorescein isothiocyanate

Description: Fluorescein isothiocyanate (FITC) is a fluorescent dye commonly used in biological research and diagnostics. It is characterized by its bright green fluorescence, which is emitted when excited by ultraviolet or blue light. FITC is a derivative of fluorescein, featuring an isothiocyanate functional group that allows it to covalently bind to proteins and other biomolecules, making it a valuable tool for labeling and tracking in various applications, including immunofluorescence and flow cytometry. The compound is soluble in organic solvents and has moderate solubility in water, which facilitates its use in aqueous biological systems. FITC is sensitive to pH and can undergo hydrolysis, leading to a decrease in fluorescence intensity over time. Its stability and reactivity make it essential for conjugation to antibodies and other macromolecules, enabling visualization of cellular structures and processes. However, care must be taken to avoid exposure to light and extreme conditions, as these can affect its fluorescent properties.
