Summary: | The present disclosure relates to methods of modifying the isoelectric point of an antibody. The method includes providing an antibody comprising a first polypeptide comprising a heavy chain variable region and a second polypeptide comprising heavy chain variable region and substituting, in at least one of the first and second polypeptides of the antibody, one or more amino acid residues of the heavy chain variable region (VH) at positions 7, 9, 11, 14, 41, 70, 74, 82a, 84, and 113, according to the Kabat numbering system, wherein the substituting increases or decreases the isoelectric point of the antibody. |
