(57) Abstract: Provided is a method for producing a glycoprotein, which comprises culturing glycoprotein-producing cells in a medium to which a galactose residue transfer regulator is added to produce the glycoprotein. [Effect] In the production of glycoprotein, the sugar chain synthesis activity is controlled, the structure of the glycoprotein sugar chain is controlled, and sugar chains and glycoproteins having the desired type and structure are obtained more uniformly and in large quantities. Becomes possible. |
