fluorescein isothiocyanate isomer ii

Description:

Fluorescein isothiocyanate isomer II (CAS 3326-31-6) is a fluorescent dye commonly used in biological and biochemical applications, particularly in labeling proteins and antibodies for fluorescence microscopy and flow cytometry. This compound is characterized by its bright green fluorescence, which is attributed to its fluorescein core structure. It contains an isothiocyanate functional group, which facilitates covalent bonding to amino groups in proteins, making it an effective labeling agent. The dye is soluble in water and organic solvents, allowing for versatile applications in various experimental conditions. Its stability under physiological conditions and high quantum yield contribute to its popularity in research. However, like many fluorescent dyes, it may be sensitive to photobleaching and pH changes, which can affect its fluorescence intensity. Safety considerations should also be taken into account, as isothiocyanates can be reactive and potentially hazardous. Overall, fluorescein isothiocyanate isomer II is a valuable tool in molecular biology for visualizing and tracking biomolecules.
