I. [Product Description]
CCK8-PEG-NOTA is a high-purity organic intermediate, which is formed by the covalent coupling of cholecystokinin octapeptide with the macrocyclic ligand NOTA through polyethylene glycol (PEG). This compound combines the targeting ability of polypeptides, the dissolution stability of PEG chains, and the metal chelating ability of macrocyclic ligands. It can be used as a pharmaceutical intermediate or a catalyst carrier, and is widely used in the fields of bioconjugation and molecular probe development.
