    摘要: A method for radiolabelling peptides using polyaminocarboxylate ligands having suitable protecting groups such that they can be added to peptides by standard solid phase or solution phase peptide synthetic chemistry and can be deproteced using standard cleavage/deprotection reagents and produce the peptide/chelate conjugate as a high purity monoaddition product is provided. The cleaved and deprotected ligand-peptide molecules can then be labeled with lanthanide or actinide radionuclides. The protected polyaminocarboxylate ligands form mono-anhydrides or mono-active esters under solid phase or solution phase conditions and permit only the desired monoaddition chelate-peptide conjugate to be formed.
