CA 2347833
Antibody variants of parent antibodies are disclosed which have one or more amino acids inserted in a hypervariable region of the parent antibody and a binding affinity for a target antigen which is at least about two fold stronger than the binding affinity of the parent antibody for the antigen.
L'invention concerne des variants d'anticorps par rapport à des anticorps d'origine, caractérisés en ce qu'un ou plusieurs acides aminés sont insérés dans une région hypervariable de l'anticorps d'origine, et présentant une affinité de liaison vis-à-vis d'un antigène cible au moins deux fois plus forte que l'affinité de liaison de l'anticorps d'origine pour l'antigène considéré.
