Antibodies Comprising Chimeric Constant Domains

Abstract

Antibodies, antigen-binding proteins and Fc-fusion proteins that comprise recombinant polypeptides containing a chimeric heavy chain constant region sequence are provided that bind to certain Fc receptors however have reduced effector functions. Methods of making constructs for expression of such chimeric Fc-containing antibodies, antigen-binding proteins and Fc-fusion proteins in cell systems, and methods of producing and isolating the chimeric Fc-containing proteins are provided.
