CAS 3301-79-9: 6-Carboxyfluorescein

Description: 6-Carboxyfluorescein is a fluorescent dye commonly used in biochemical and molecular biology applications. It is characterized by its bright green fluorescence, which is attributed to its xanthene structure. The compound has a carboxylic acid functional group, which enhances its solubility in aqueous solutions, making it suitable for various biological assays. Its fluorescence properties make it an excellent choice for labeling biomolecules, tracking cellular processes, and as a tracer in flow cytometry. The dye exhibits a high quantum yield and is relatively stable under physiological conditions, although it can be sensitive to pH changes and light exposure. Additionally, 6-Carboxyfluorescein can be conjugated to proteins or nucleic acids, allowing for versatile applications in imaging and detection. Its ability to undergo resonance energy transfer also makes it useful in fluorescence resonance energy transfer (FRET) studies. Overall, 6-Carboxyfluorescein is a valuable tool in research for visualizing and quantifying biological interactions and processes.
