Abstract

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