Abstract

A method of preparing a hydrogel product including crosslinked glycosaminoglycan molecules, said method including: i) providing a glycosaminoglycan crosslinked by amide bonds, wherein the crosslinked glycosaminoglycans include residual amine groups; and ii) acylating residual amine groups of the crosslinked glycosaminoglycans provided in i) to form acylated crosslinked glycosaminoglycans.
