DBCO-Cyanine7 is widely used in bioimaging and bioconjugation due to its near-infrared fluorescence properties, making it ideal for deep tissue imaging. It is commonly employed in labeling biomolecules such as proteins, antibodies, and nucleic acids for tracking and visualization in live cells and animal models. The DBCO group enables efficient, copper-free click chemistry reactions with azide-modified molecules, ensuring rapid and specific conjugation without toxicity. This makes it valuable in drug delivery studies, molecular diagnostics, and the development of targeted therapies. Its stability and high fluorescence intensity also support its use in multiplexed imaging and long-term tracking experiments.
