Provided are antibody variants having decreased or increased ability to mediate complement-dependent cytotoxicity (CDC) due to the presence or absence of C-terminal lysines of their heavy chains. Also provided are methods of generating such antibodies, as well as nucleotide constructs and host cells suitable for the production of such antibodies.
