Halt™ Protease Inhibitor Cocktail (100X), 5 mL

Q: Can I use just part of the Pierce Protease Inhibitor XL Capsules, EDTA-Free and save part of the capsule for later use?

We do not recommend splitting the capsule into smaller portions. Researchers using less than 500 mL should choose a different format (liquid or tablet) of protease inhibitors. Find additional tips, troubleshooting help, and resources within our Protein Purification and Isolation Support Center .
