Abstract

See full text

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 reaction of a galactose residue to a non-reducing terminal acetylglucosamine 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.
