CELL WITH DEPRESSION OR DELETION OF THE ACTIVITY OF PROTEIN PARTICIPATING IN GDP-FUCOSE TRANSPORT

摘要

A cell in which the activity of a protein participating in the transport of an intracellular sugar nucleotide GDP-fucose into Golgi bodies is depressed or deleted compared with its parent strain cells; a process for producing an antibody composition with the use of the above cell; a transgenic nonhuman animal or plant the genome of which has been modified so as to depress or delete the activity of a protein participating in the transport of an intracellular sugar nucleotide GDP-fucose into Golgi bodies, or offspring thereof; a process for producing an antibody composition from the above animal or plant; and a drug containing the antibody composition.
