Patent number: 11649295Abstract: The present invention relates to multispecific antibodies, for example bispecific antibodies, and methods for the isolation or purification of the same. The antibodies of the invention comprise first and second heavy chain-light chain pairings wherein each pairing comprises a distinct selective recognition site including one or more amino acid residues contributed from the heavy chain and the light chain of the pairing. The first and second selective recognition sites differ by at least one amino acid residue and can be differentially bound by first and second selective recognition agents according to the methods of the invention. Such methods facilitate the production of antibody preparations enriched for multispecific antibodies having the correct functional heavy chain-light chain pairings.Type: GrantFiled: October 11, 2019Date of Patent: May 16, 2023Assignee: argenx BVInventors: Christophe Frederic Jerome Blanchetot, Johannes Joseph Wilhelmus De Haard
