Cyanine 5 azide

Cyanine 5 azide labeling reagent for Click Chemistry, supplied 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. Cyanine 5 is an analog of Cy5® , one of the most commonly used fluorophores which is compatible with various instruments. Cyanine 5 can also be used as a replacement for Alexa Fluor^® 647, and DyLight^® 649.
