    摘要: A method for preparing a conjugate comprising a glycoprotein and a polymer or a derivative of said polymer, wherein the polymer is a hydroxyalkylstarch (HAS), the method comprising the steps a) reacting said glycoprotein with a modified polyol carrying attached thereto, by a covalent linkage, a functional group Z, in the presence of a transferase capable of catalysing formation of a covalent linkage between the glycoprotein and said modified polyol, yielding a glycoprotein covalently linked to a polyol carrying attached thereto, by a covalent linkage, at least one functional group Z, and b) reacting at least one functional group A of the polymer or the derivative thereof with the at least one functional group Z of the glycoprotein added to said glycoprotein during step a), and thereby forming a covalent linkage.
