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.

AF 343 (Coumarin) X azide

AF 343 (Coumarin) is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by сlick chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility and provides spatial separation between the dye and the biomolecule.

DAPI, blue fluorescent nucleic acid stain

DAPI (4′,6-diamidino-2-phenylindole) is a blue-emitting fluorescent DNA dye used for chromosome staining and as a nuclear counterstain in fluorescence microscopy and flow cytometry.

sulfo-Cyanine7.5 NHS ester

A water-soluble near-infrared emitting dye for in vivo imaging applications. sulfo-Cyanine7.5 is an analog of indocyanine green (ICG) possessing higher emission quantum yield and a linker arm.
