METHOD FOR PRODUCING GLYCOPROTEIN CHARACTERIZED BY SUGAR CHAIN STRUCTURE BY USING SILKWORM

摘要

It is an object of the present invention to investigate what kinds of structures a sugar chain has by performing a sugar chain structural analysis of a glycoprotein produced in a transgenic silkworm. For the sugar chain of the glycoprotein produced in the transgenic silkworm, a glycoprotein having a sugar chain structure in which fucose is not linked to N-acetylglucosamine at a reducing terminal of the sugar chain is obtained. In addition, a glycoprotein having an almost completely humanized sugar chain structure is obtained by further integrating GalT gene into this transgenic silkworm.
