Abstract
The present invention provides a method for manufacturing a glycoprotein having a human-type sugar chain comprising a step in which transformed plant cell is obtained by introducing to a plant cell the gene of glycosyltransfetase and the gene of an exogenous glycoprotein, and a step in which the obtained transformed plant cell is cultivated.
Claims13
A plant-produced glycoprotein having a human-type sugar chain, obtained from a transformed plant cell, wherein the transformed plant cell was produced by:
- introducing to a plant cell a gene encoding a galactosyltransferase enzyme and a gene of an exogenenous glycoprotein;
- cultivating the transformed plant cell;
- and when desired separating the resulting glycoprotein.
A plant-produced glycoprotein comprising no fucose or xylose linked to one or more of the core sugar chain, the outer sugar chain and the terminal sugar chain.
