摘要： A means of controlling sugar chain-modification and sugar chain structure in the production of a glycoprotein with the use of gene recombination techniques. A process for producing a glycoprotein by culturing a gene recombinant host in a medium characterized in that the relative sugar consumption speed is employed as an indication and changed to thereby modify the sugar chain structure attached to the protein.
