methods for increasing and decreasing an effector function of a parental polypeptide and a parent antibody, for enhancing an effector function of a combination of at least one first and a second parent polypeptide, for inducing an effector response against a cell, cell membrane, or virion, to increase the specificity of a combination of at least a first and a second parent polypeptide, variant of a parent polypeptide, composition, and part kit

摘要

Described herein are polypeptides and related antibodies comprising a variant Fc domain. The variant Fc domain provide for stabilized Fc:Fc interactions when the polypeptide(s), antibody or antibodies are bound to its target, antigen or antigens on the surface of a cell, thus providing for improved effector functions, such as CDC-response.
