A water-soluble protein conjugate modified by saccharides is covalently bound to a carbohydrate backbone via a saccharide group. Such protein conjugates modified by saccharides can be produced in a simple way by polymerizing a vinylsaccharide and conjugating in a known way the poly(vinylsaccharide) obtained in this way with the protein, which is preferably an enzyme. The protein conjugates according to the present invention are stable over long time periods at a high enzymatic activity and also in aqueous solution and are thus particularly suitable for use in test kits.
