cyanine7 azide

Cyanine7 azide is a potent fluorescent dye employed for near-infrared in vivo imaging (λex=756 nm, λem=779 nm). It serves as a click chemistry reagent, featuring an azide group that enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) with alkyne-containing molecules. Additionally, it can participate in strain-promoted azide-alkyne cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.

Cyanine7 azide chloride, a fluorescent marker within the cyanine dye series, is commonly used for biomolecule interactions. Cyanine dyes can also bind to double-helical DNA through intercalation, resulting in enhanced fluorescence upon binding.

CY7-N3 (Sulfo-Cyanine7-N3) is a CY7 derivative for click chemistry, containing an azide group capable of undergoing CuAAc reactions with molecules bearing alkyne groups, or SPAAC reactions with molecules containing DBCO or BCN groups. CY7 is an amine-reactive, near-infrared (NIR) fluorophore commonly used for fluorescent labelling of proteins and nucleic acids.

Cyanine7 alkyne (Cyclohexene) is a near-infrared fluorescent dye containing an alkynyl (-C≡C-) functional group. It is suitable for specific binding to biological molecules containing an azide group (-N₃) through click chemistry and is commonly used in biolabeling, imaging and analysis.
