    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.

    摘要: An inhibitor of the aggregation of immunoglobulin chains is provided. The inhibitor may comprise or consist of a polypeptide which comprises or consists of (a) an amino acid sequence corresponding to the amino acid sequence of the FR1 region of an immunoglobulin light chain variable domain, or part thereof which includes amino acid residue 12, (b) an amino acid sequence corresponding to the amino acid sequence of the immunoglobulin-binding domain of bacterial superantigen Protein L, or part thereof, and/or (c) an amino acid sequence corresponding to the amino acid sequence of the immunoglobulin-binding domain of streptococcal protein G, or part thereof, or a variant, fusion or derivative thereof, or a fusion of a variant or derivative thereof which retains the ability of the parent polypeptide to inhibit aggregation of immunoglobulin chains, or domains thereof. Other versions of the inhibitor are also provided.
