Cy5.5 is a fluorescent dye used in biological research, particularly for imaging and detection purposes. It belongs to the cyanine dye family and is characterized by its strong fluorescence in the far-red to near-infrared spectrum. This makes it suitable for applications where minimal background interference is desired, such as in vivo imaging and fluorescence microscopy. Cy5.5 is known for its photostability and high extinction coefficient, which allows for sensitive detection even at low concentrations. It is commonly used for labeling antibodies, proteins, and other biomolecules to track their distribution and interactions within biological systems.
