Cyanine3.5 is a fluorescent dye with absorption and emission intermediate between Cyanine3 and Cyanine5. The sulfonated version contains four sulfo groups, which ensure high solubility and hydrophilicity of the fluorophore and labeled conjugates.

The NHS ester reactive group allows labeling of primary and secondary amine groups.
