Sulfo-Cyanine 5.5 is a water-soluble, hydrophilic fluorophore which possesses emission in far red area of the spectrum, an analog of Cy5.5. As with other cyanine dyes, sulfo-Cyanine 5.5 has an outstanding molar extinction coefficient which gives rise to its bright fluorescence. The molecule contains four sulfo groups that provide hydrophilicity and negative charge to the fluorophore - this minimizes non-specific binding. The azide group of sulfo-Cyanine 5.5 azide can be conjugated with terminal alkynes in the presence of copper(I) catalyst, or with cycloalkynes in copper free strain promoted reaction.
