JP104 is widely used in molecular biology and biochemistry for labeling and tracking biomolecules. It is particularly effective in fluorescence-based assays, where it serves as a fluorescent tag to visualize proteins, nucleic acids, and other cellular components under microscopy. Its high photostability and brightness make it suitable for live-cell imaging, allowing researchers to monitor dynamic processes in real time. Additionally, JP104 is utilized in flow cytometry to analyze and sort cells based on specific markers. Its compatibility with various conjugation chemistries enables its attachment to antibodies, peptides, or other probes, enhancing its versatility in diagnostic and research applications.
