A glycan-modified antibody comprising N-linked glycans attached to a variable region of said antibody, wherein said antibody comprises a heavy chain comprising three CDRs contained in SEQ ID NO:
- 2 and a light chain comprising three CDRs contained in SEQ ID NO:3, and comprises an engineered N-linked glycosylation site at an amino acid position in the sequence of SEQ ID NO:3 selected from the group consisting of amino acid 54 of SEQ ID NO:3 (30EGln), amino acid 77 of SEQ ID NO:3 (52Ser), amino acid 78 of SEQ ID NO:3 (53Thr), amino acid 79 of SEQ ID NO:3 (54Arg), amino acid 85 of SEQ ID NO:3 (60Asp), amino acid 90 of SEQ ID NO:3 (65Ser), amino acid 92 of SEQ ID NO:3 (67Ser), and amino acid 101 of SEQ ID NO:3 (76Ser).
A glycan-modified antibody comprising N-linked glycans attached to a variable region of said antibody, wherein said antibody comprises a light chain and a heavy chain, wherein said light chain comprises an amino acid sequence of the light chain set forth in SEQ ID NO:4 and wherein said heavy chain comprises an amino acid sequence of the heavy chain as set forth in SEQ ID NO:
- 5.
