Application: EDTA is an inhibitor of metalloproteases, at effective concentrations of 1-10 mM. EDTA acts as a chelator of the zinc ion in the active site of metalloproteases, and can also inhibit other metal ion-dependent proteases such as calcium-dependent cysteine proteases. For use as an anticoagulant, disodium or tripotassium salts of EDTA are most commonly used. The optimal concentration is 1.5 mg per ml of blood.
Preparation Note: Soluble in water at room temperature up to 1.45 M. The pH of this solution will be approximately 10 to 11 and will be rather viscous.
