Cyanine 3.5 is a fluorescent dye with absorption and emission intermediate between Cyanine 3 and Cyanine 5. Sulfonated version contains four sulfo groups which ensure high solubility and hydrophilicity of the fluorophore and labeled conjugates. The NHS ester reactive group allows to label primary and secondary amine groups.
