CAS 18861-78-4: fluorescein isothiocyanate isomer ii

Description: Fluorescein isothiocyanate isomer II (CAS 18861-78-4) is a fluorescent dye commonly used in biological and biochemical applications, particularly for labeling proteins and antibodies. This compound is characterized by its bright green fluorescence, which is a result of its unique chemical structure that includes a fluorescein moiety. It is soluble in organic solvents and water, making it versatile for various experimental conditions. The isothiocyanate functional group allows for covalent bonding to amino groups in proteins, facilitating the creation of fluorescent conjugates. Fluorescein isothiocyanate isomer II is known for its stability under physiological conditions, although it can be sensitive to light and pH changes. Its fluorescence properties make it an invaluable tool in microscopy, flow cytometry, and other imaging techniques, enabling researchers to visualize and track biological processes in real-time. Proper handling and storage are essential to maintain its efficacy, as exposure to light and moisture can lead to degradation.
