Purification of optical imaging ligand-Cybesin by high-speed counter-current chromatography [PDF]
Journal of Chromatography B, 2010 Fluorescent Cybesin (Cypate-Bombesin Peptide Analogue Conjugate) was synthesized from Indocyanine Green (ICG) and the bombesin receptor ligand as a contrast agent for detecting pancreas tumors. However, the LC-MS analysis indicated that the target compound was only a minor component in the reaction mixture.
