Biological Activity

CY5-SE is an amine-reactive cyanine fluorescent dye that reacts covalently with primary amine groups to form a stable amide linkage. This covalent labeling allows robust fluorescent tracking of proteins, biomolecules, and cellular components. Furthermore, CY5-SE-functionalized systems can be integrated into chemo-photothermal therapeutic platforms to facilitate light-triggered bacterial killing and target drug-resistant pathogens. [1]
