Calcein (mixture of isomers)（Cat No.:R019361）is a fluorescent dye commonly used in biological and biochemical research. It exhibits strong fluorescence in the green spectral range, making it useful for tracking cells, tissues, and biomolecules. The dye is a mixture of different isomers, each with slightly varying fluorescence properties. Calcein is widely employed for live-cell imaging, membrane potential assays, and intracellular ion concentration measurements. It is also used in flow cytometry to study cell viability and cellular processes. Its bright fluorescence and stability make it an excellent tool for visualizing dynamic biological events in real-time.
