    摘要: The present invention relates to a method for reducing the fucose content of a recombinant protein, which comprises expressing in an animal cell the recombinant protein and FUCA1, an FUCA1 mutant, FUCA2, or a fragment of FUT8 localization domain; or with a fusion protein of a fragment of FUT8 localization domain and a fragment of FUCA1, a FUCA1 mutant or FUCA2. Therefore, the antibody expressed according to the method of the present invention exhibits a reduced fucose content in their Fc regions, which leads to the improvement in the therapeutic effect thereof.
