diSulfo-Cy5 azide

Description

diSulfo-Cy3 azide is a water-soluble dye containing an azide group, which enables Click Chemistry. Absorbance and emission of the dye are identical to Cy3 fluorophore. The reagent is designed for the labeling of sensitive molecules such as proteins, and even intact biological objects in water phase.

Uses

Sulfo-cyanine3 azide sodium a water-soluble azide cyanine dye and fluorescent probe (Ex/Em=548/563 nm). Sulfo-cyanine3 azide sodium can be involved in synthesis of fused tricyclic heterocycles, produces immunostimulatory agents[1][2]. It contains an azide group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing alkyne groups. It can also undergo ring strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.
