    Background
    
    Cy5.5 alkyne (non-sulfonated) is a far red/near infrared dye alkyne with an ethynyl group for Click Chemistry labeling. Cyanine5.5 is an analog of Cy5.5®, a popular fluorophore which has been widely used for various applications including intact organism imaging. Cy5.5 alkyne (non-sulfonated) can be conjugated with azido groups under mild copper catalyzed Click Chemistry conditions.
    Cy5.5 alkyne (non-sulfonated) is soluble in organic solvents, but mixtures of water with small percent of DMSO can be used for efficient conjugation. Cy5.5 alkyne (non-sulfonated) can also be used for the labeling of small molecules.
