ANTIBODIES WITH ENHANCED OR SUPPRESSED EFFECTOR FUNCTION

摘要

Rationally designed antibodies and polypeptides that comprise two Fc region amino acid substitutions that synergistically provide enhanced selectivity and binding affinity to a target Fc receptor are provided. The polypeptides comprise Fc region mutations at two positions that synergistically make the polypeptides more effective when incorporated in antibody therapeutics than those having wild-type Fc components.
