Sulfo-Cy5 carboxylic acid bromide is a Cy5 derivative that can be used for chemical synthesis. Cy5 is a red fluorescent label dye for imaging (Ex/Em=642/670 nm) [1].
In Vitro, Sulfo-Cy5 carboxylic acid bromide is commonly used as a fluorescent labeling intermediate, enabling further conjugation to proteins, peptides, nucleic acids, or other biomolecules via the carboxyl group.
