Sulfo-Cyanine5.5 is a fluorescent dye that is commonly used in biological imaging and detection applications. It belongs to the class of cyanine dyes, which are characterized by their bright fluorescence, high photostability, and low cytotoxicity. Sulfo-Cyanine5.5 is a water-soluble derivative of Cyanine5.5, which enables its use in aqueous environments such as biological fluids, cell cultures, and tissues.
Sulfo-Cyanine5.5 emits a red light with a peak wavelength of approximately 675 nanometers when excited by a light source at around 645 nanometers. This unique optical property makes it suitable for a variety of applications such as fluorescent labeling of biomolecules, cell tracking, and in vivo imaging. Its bright fluorescence and excellent photostability allow for long-term imaging and detection of biological processes.
Furthermore, Sulfo-Cyanine5.5 is highly versatile and can be conjugated to a wide range of biological molecules including proteins, antibodies, peptides, and nucleic acids. This enables researchers to selectively label and track specific biomolecules in complex biological systems.
