This chemical is primarily utilized as a fluorescent labeling agent in biochemical and molecular biology research. It is commonly employed to tag proteins, nucleic acids, and other biomolecules, enabling their detection and analysis under fluorescence microscopy or flow cytometry. Its high fluorescence intensity and stability make it suitable for tracking cellular processes, studying protein interactions, and visualizing molecular dynamics in live or fixed cells. Additionally, it is used in immunoassays and diagnostic applications to enhance the sensitivity and accuracy of detection methods. Its ability to bind specifically to target molecules while maintaining fluorescence properties makes it a valuable tool in advanced research and diagnostic techniques.
