The present invention relates to 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.

L'invention concerne un procédé permettant de préparer un conjugué comprenant une glycoprotéine et un polymère ou un dérivé de celui-ci, ledit polymère étant un amidon hydroxyalkylé (AS). Le procédé consiste: a) à faire réagir la glycoprotéine avec un polyol modifié, portant un groupe fonctionnel Z qui lui est attaché au moyen d'une liaison covalente, en présence d'une transférase capable de catalyser la formation d'une liaison covalente entre la glycoprotéine et le polyol modifié, et donnant une liaison glycoprotéine liée par liaison covalente au polyol modifié portant au moins un groupe fonctionnel Z qui lui est attaché au moyen d'une liaison covalente, et b) à faire réagir au moins un groupe fonctionnel A du polymère ou de son dérivé avec au moins le groupe fonctionnel Z de la glycoprotéine qui lui est ajouté pendant l'étape a), ce qui permet de former un liaison covalente.
