the effect of antitrombootilise polysaccharides having at least one of a covalent bond biotin v? i biotin derivatives

摘要

The present invention relates to novel synthetic polysaccharides with antithrombotic activity exhibiting at least one covalent bond with biotin or a biotin derivative and to a process employing avidin or streptavidin which makes it possible to neutralize these polysaccharides.
