85-1537-63　［取扱停止］Aprotinin, Bovine (US/North America) (Pancreatic trypsin inhibitor) 250mg　CAS No:9087-70-1　A2300-04

特徴

• 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 glycoprotein loss (e.g., GpIb, GpIIb/IIIa), while in granulocytes it prevents the expression of pro-inflammatory adhesive glycoproteins
• Aprotinin is a natural proteinase inhibitor polypeptide consisting of 58 amino acids arranged in a single polypeptide chain, cross-linked by three disulfide bridges and having a molecular mass of 6512D.
