Far red / near-infrared dye alkyne for сlick сhemistry labeling. Cyanine5.5 is an analog of Cy5.5®, a popular fluorophore widely used for various applications, including intact organism imaging. This reagent can be conjugated with azido groups under mild copper-catalyzed сlick сhemistry conditions.
This reagent is soluble in organic solvents, but mixtures of water with a small percent of DMSO can be used for efficient conjugation. Cyanine5.5 alkyne can also be used for the labeling of small molecules with this far red/NIR dye.
