cy7 n3

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.

Sulfo Cy7-N3 is a Sulfo Cy7-azide compound and functions as a fluorescent dye. It can be employed in cell imaging through click reactions. The molecule contains an azide group, enabling it to engage in a copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules that have an alkyne group. Additionally, it can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules possessing DBCO or BCN groups.
