Aprotinin is a reversible inhibitor of serine proteases such as trypsin (Ki = 0.06 pM), chymotrypsin (Ki = 9.5 nM), and kallikrein (Ki = 0.8 nM). It is a much weaker inhibitor of thrombin (Ki = 0.1-0.8 mM) and trypsinogen (Ki = 2 µM). Aprotinin also competitively inhibits nNOS and iNOS with Ki values of 50 and 78...

A pancriatic basic trypsin inhibitor polypeptide found in tissues and blood.

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...

Aprotinin inhibits the activity of several proteolytic enzymes such as chymotrypsin, kallikrein, plasmin and trypsin. It is present in blood and in most tissues, with a high concentration in lung, inhibits pro-inflammatory cytokine release and maintains glycoprotein homeostasis. In platelets, aprotinin reduces...
