Opis

General description

A competitive and reversible inhibitor of esterase and protease activity. Forms a tight complex with and blocks the active site of target enzymes. Inhibits a number of different proteases, including chymotrypsin, coagulation factors involved in the pre-phase of blood clotting, kallikrein (K_d = 1 X 10^-7 M), plasmin (K_d = 2.3 X 10^-10 M), tissue and leukocyte proteinases, and trypsin (K_d = 5 X 10^-14 M). Does not inhibit Factor Xa or thrombin. Reported to be relatively acid and heat stable. Effectively inhibits target proteases at equimolar concentration. Useful as a serine proteinase inhibitor during purification of proteins and in studies of zymogen activation systems. Reported to suppress virus HA cleavage and limit reproduction of human and avian influenza viruses with a single arginine in the HA cleavage site.

Effectively inhibits target proteases at equimolar concentration.

Note: 1 KIU = 0.025 antiplasmin units (APU) = 0.0016 trypsin inhibitor units (using porcine trypsin) = 0.0009756 trypsin inhibitor units (using bovine trypsin).

Biochem/physiol Actions

Kd = 1 x 10-7 M, 2.3 x 10-10 M, 5 x 10-14 M, against kallikrein, plasmin, and trypsin, respectively

Primary Target
chymotrypsin

Preparation Note

Following reconstitution refrigerate (4°C). Stock solutions are stable for up to 3 months at 4°C.

Other Notes

One Kallikrein Inhibitory Unit (K.I.U.) is defined as the quantity of protease inhibitor that will inhibit two kallikrein units by 50% under optimal conditions. Note: 1 KIU = 0.025 antiplasmin units (APU) or 0.0031 trypsin inhibitor units.
