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), so labeling reaction should be carried out with small amount of organic co-solvent. This azide can be used for the labeling of alkyne-modified biomolecules in mixtures of water with organic solvents. Solution in DMSO is ready form for the use in bioconjugation. Water-soluble 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 is also a replacement dye for Alexa Fluor 647, and DyLight 649.
