| abstract |
A modified antibody molecule which selectively binds to a specific target, the antibody molecule being modified at, at least one amino acid residue that forms part of a glycosylation site in the variable region of an unmodified parent antibody molecule, characterised in that the modified antibody is not glycosylated at the previous glycosylation site of which the amino acid modification forms part and the modified antibody exhibits a greater binding affinity for the specific target than the unmodified parent antibody molecule. There is also provided nucleotide sequences, amino acid sequences and expression vectors encoding the modified antibodies, and uses thereof. |
