Cyanine7 azide is a near-infrared fluorescent dye azide for Click Chemistry labeling, an analog of Cy7® azide.
This product can be used for the incorporation of Cyanine7 into various alkynylated biomolecules via Click Chemistry. Post-synthetic modification of oligonucleotides is also possible with this azide.
Cyclohexane-bridged polymethyne chain allows for 20% increase in quantum yield (compared to parent non-bridged structure).
