    摘要: The invention relates to a method for providing a multispecific peptide ligand comprising a polypeptide covalently linked to a molecular scaffold at three or more amino acid residues and capable of binding to two or more separate targets, comprising the steps of: (a) providing a first repertoire of polypeptides, each polypeptide comprising two or more reactive groups capable of covalent linkage to a molecular scaffold, and at least one loop which comprises a sequence of two or more amino acids subtended between two of said reactive groups; (b) providing a second repertoire of polypeptides as described in (a); (c) joining at least one loop of one or more members of the first repertoire to at least one loop of one or more members of the second repertoire to form at least one polypeptide comprising two loops, and (d) conjugating the composite polypeptide(s) to a molecular scaffold at at least three amino acid positions.
