Use | EDTA is a metalloprotease inhibitor with an effective concentration of 1-10mm. EDTA can be used as a chelating agent for the active center zinc ion of metalloproteases, and can also inhibit other metal ion-dependent proteases, such as calcium-dependent cysteine proteases. As an anticoagulant, The disodium or tripotassium salt of EDTA is usually used. The optimal concentration is 1.5mg per mL of blood. |
