ULTRA-PURE POLYSACCHARIDE MATERIALS FOR MEDICAL USE

摘要

A process for purifying polysaccharides includes forming a 1% solution of medial grade polysaccharides and passing them through three filters. The first and second filters being nitrocellulose filters whith the third filter being modified with polypeptides to bind hydrophobic impurities. The resulting solution is then dialyzed to remove low molecular weight impurities.
