Aprotinin is a broad spectrum serine protease inhibitor used in diagnostics applications to prevent proteolytic degradation. It exhibits high specific activity against trypsin, chymotrypsin, plasmin and kallekrein. Used in diagnostic systems to prevent proteolytic damage in downstream purification of proteins and serum-free media.
