Abstract
The present invention is directed to modified antibodies, including anti-TNFα antibodies, in which C-terminal amino acids of heavy chain sequences are modified from a native sequence of proline-glycine-lysine ('PGK') to one that includes a proline positioned between the glycine and lysine, resulting in a C-terminal sequence of proline-glycine-proline-lycine ('PGPK'). The invention further provides methods of producing and using such antibodies.
