Background

Cy7 carboxylic acid is a near-infrared fluorescent dye which has low aqueous solubility. As for coupling and labeling reactions, pre-activated Cy7 NHS ester or water-soluble sulfo-Cy7 NHS ester would be considered. For biomolecule labeling, the labeling reagent has low aqueous solubility, using of organic co-solvent to dissolve this molecular is necessary for efficient reaction. First, Cyanine dye should be dissolved in organic solvent and then added to a solution of biomolecule in appropriate aqueous buffer.

Cy7, together with carboxylic acid (CA) make up the model drugs. On the basis of this, the study was able to estimate the amount of Cy7 carboxylic acid on the particle through direct emission spectra measurements [1].
