Description

Description générale

Recombinant, bovine aprotinin supplied without animal-derived components. Aprotinin is a competitive, reversible inhibitor of proteolytic and esterolytic activity. A relatively heat- and acid-stable serine protease inhibitor. Forms a tight complex, blocking the active site of the enzyme. Effective at concentrations equimolar with protease. Inhibits several proteases, including coagulation factors in the prephase of blood clotting, tissue and leukocytic proteinases, chymotrypsin, trypsin (K_d = 5 x 10^-14 M), plasmin (K_d = 2.3 x 10^-10 M), and kallikrein (K_d = 1 x 10^-7 M). Proteases not inhibited by aprotinin include Factor Xa, thrombin, pepsin, papain, and carboxypeptidases A and B. Useful for protein purification and for extending the life of cells in culture by preventing proteolytic damage.
