Described is a method of production of saccharides containing sialic acid, wherein beta -galactoside- alpha -2,6-sialyltransferase is used for linking sialic acid to the 6-position of a galactose residue in a sugar chain of a glycoconjugate or the 6-position of a galactose residue in a free sugar chain, or to the 6-position of a monosaccharide having a hydroxyl group on carbon at the 6-position and being capable of forming an oligosaccharide or a glycoconjugate. |
