Sulfo-Cyanine5.5 carboxylic acid potassium

Fluorescent Dye

Sulfo-Cyanine5.5 carboxylic acid potassium is a fluorescent dye characterized by its excitation and emission wavelengths of 673 nm and 707 nm, respectively. The incorporation of a sulfite group significantly improves the compound's hydrophilicity, facilitating its application in aqueous environments. The terminal carboxylic acid group can readily react with primary amines, especially in the presence of coupling agents like EDC and HATU, enabling the formation of stable amide bonds for various biochemical applications, including labeling and tracking biomolecules in research studies.
