Can absolute ethanol suppress the activity of Proteinase K?

09 May 2017 1 2K Report

sample was kept in absolute ethanol, if i can use Proteinase K deal with this sample?

Are you trying to extract DNA from the sample? If so, you should have no problem. We routinely extract DNA from fish fin clips that are stored in absolute ethanol and we don't see any problem with Proteinase K activity.
