A water-soluble, azide-reactive probe.
Cy5.5 DBCO dye reacts with azides via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalysts or elevated temperatures. In applications where the presence of copper is a concern, Cy5.5 DBCO is an ideal alternative to copper requiring fluorescent alkynes.
Cy5.5 DBCO reagent is not suitable for staining intracellular components of fixed and permeabilised cells due to high backgrounds.
