What is the optimal temperature for activating proteinase K?

Posted September 7, 2023


Answer

The optimal temperature for activating proteinase K is 50-65 degrees celsius. Higher temperatures facilitate the unfolding of contaminant proteins and nucleases, and increase the ability of proteinase K to neutralize unwanted proteins.
