Recombinant aprotinin
Serine protease inhibitor, same sequence as bovine aprotinin.
A competitive inhibitor of trypsin, chymotrypsin and kallikrein with the same amino-acid sequence as aprotinin from bovine lung. It replaces animal-derived aprotinin in biotech processes, for example to stop trypsin digestion.
