Cyanine3 alkyne is a fluorophore ready for the use in Click Chemistry reaction.

With this reagent, bright and photostable Cyanine3 reporter, an analog of Cy3®, can be attached to nearly any molecule bearing azide group.

This alkyne is non water-soluble. However, when used with organic co-solvent (DMSO or DMF), this dye can be efficiently attached to water-soluble molecules such as proteins, or peptides.
