Widely used as a fluorescent probe in biological research, this compound is particularly effective for labeling and tracking biomolecules such as proteins and nucleic acids. Its strong fluorescence and high sensitivity make it suitable for imaging cellular structures and monitoring dynamic processes within living cells. It is commonly employed in fluorescence microscopy and flow cytometry due to its ability to bind selectively to specific molecular targets. Additionally, it serves as a key reagent in assays that require real-time detection of enzymatic activity or molecular interactions. Its stability under physiological conditions enhances its reliability in long-term experiments.
