Can I store the unopened, lyophilized PTMScan® LysC Protease #84748 at -80°C instead of -20°C?

Yes, the lyophilized PTMScan® LysC Protease #84748 may be stored at -80°C. However, we do not recommend storing the LysC powder in a frost-free freezer or a freezer that undergoes freeze-thaw cycles. Prior to use, we recommend bringing the vial containing the lyophilized powder to room temperature for resuspension. Therefore, storing the protease at a colder temperature may require a few additional minutes of temperature equilibration before resuspension.
