Cy5.5 DBCO is an azide reactive probe used for imaging azide-tagged biomolecules via a copper-free “click reaction”. DBCO moiety reacts with azides to form a stable triazole and does not require Cu-catalyst or elevated temperatures allowing detection of azide-tagged biomolecules under mild conditions. In application where the presence of copper is a concern Cy5.5 DBCO is an ideal alternative to copper requiring fluorescent alkynes.

Cy5.5 DBCO is a bright and photostable near-IR probe that spectrally similar to Alexa Fluor® 680, DyLight® 680, and IRDye® 680 dye. The Cy5.5 DBCO is water-soluble, hydrophilic dye often a reagent of choice for assay where minimal non-specific binding and exceptional brightness is required. The fluorescence of Cy5.5 DBCO is pH insensitive from pH 4 to pH 10 and produces minimal autofluorescence of biological specimens in this region of the spectrum. Fluorescence of this long-wavelength Cyanine dye is not visible to the human eye but is readily detected by most imaging systems.

Cy5.5 DBCO reagent is not suitable for staining intracellular components of fixed and permeabilized cells due to high backgrounds.
