A method for the secretory production of a glycoprotein having a human-type sugar chain, comprising a step of introducing a gene of an enzyme capable of performing a transfer 5 reaction of a galactose residue to a non-reducing terminal acetyl-glucosamine residue, and a gene of heterologous glycoprotein, to obtain a transformed plant cell, a step of culturing the plant cell, and a step of recovering the culture medium of the plant cell. |
