Background

Sulfo-Cy7 NHS ester is a sulfonated, hydrophilic and highly water soluble dye. This reagent allows prepare Cy7-labeled biomolecules, especially useful for the labeling of delicate proteins, and proteins prone to denaturation. Dye labeled molecules can be used for kinds of researches related experiments. Near infrared fluorescent imaging takes advantage of transparency of biological tissues at particular range of wavelengths. In live organisms, the method is non-destructive, and allows monitor distribution of various labeled molecules. Non-sulfonated Cy7 NHS ester soluble in organic phase is also available. For labeling proteins and peptides, no organic co-solvent is needed. 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 mice, Cy7-labeled RIG precursor solution and Cy7-labeled PIC micelles solution, was analyzed with an IVIS spectrum system. Administration of the Cy7-labeled RIG resulted in strong fluorescence signal in the mouth as compared with the orally administered Cy7-labeled PIC micelles solution [1].
