Background:

Sulfo-Cy3 NHS ester is a sulfonated, hydrophilic and highly water soluble dye. For labeling proteins and peptides, no organic co-solvent is needed. Sulfo-Cy3 NHS ester is ideal for proteins with low solubility and proteins prone to denaturation. Non-sulfonated Cy3 NHS ester is also available. In life science, the sulfonate groups make the Cy dyes soluble in water and also reduce fluorescence-quenching which can arise from dye–dye interactions.

In vitro, sulfo-Cy3 NHS ester can react with green-emitting QDs ligand-exchanged and LA/His-PIMA-PEG-NH2 to provide QD-dye conjugates [1].
