WebInactivating proteinase K is perhaps one of the most common questions we see. And the answer is very simple. Heat is a widely used way of inactivating proteinase K. While the activity of proteinase K increases with temperature, and is optimized at about 65 ˚C, heating proteinase K to 95 ˚C for 10 minutes will inactivate it. WebJan 1, 1997 · Ethylenediaminetetraacetic acid (EDTA), which complexes divalent ions, is a poor stabilizing agent to prevent ex vivo generation of C4a, whereas Futhan (nafamostat mesilate)—a powerful serine protease inhibitor—is an excellent stabilizing agent in this regard. On the other hand, heparin, when combined with EDTA, significantly reduces ex …
