Cyanine5 azide labeling reagent for Click Chemistry, available as 10 mM solution in DMSO and in solid form.

This azide is soluble in organic solvents (e.g., DMSO, DMF); therefore, the labeling reaction should be carried out with a small amount of an organic co-solvent. This azide can be used for the labeling of alkyne-modified biomolecules in mixtures of water with organic solvents. The solution in DMSO is ready for use in bioconjugation. A water-soluble sulfonated version of this reagent is also available.

Cyanine5 is an analog of Cy5®, one of the most commonly used fluorophores, which is compatible with various instruments. Cyanine5 can also be used as a replacement for DyLight® 649.
