Protease Inhibitor
Protease Inhibitor — A molecule that blocks the activity of proteases, used in research to prevent unwanted peptide degradation during sample preparation and storage.
What Is a Protease Inhibitor?
A protease inhibitor is a molecule that blocks the activity of endopeptidases or exopeptidases. In peptide research, protease inhibitors serve two purposes: protecting peptides from degradation during sample preparation and biological assays, and as therapeutic agents targeting disease-relevant proteases (HIV protease inhibitors, DPP-IV inhibitors for diabetes).
Common Protease Inhibitor Cocktails
- AEBSF: Serine protease inhibitor (replaces toxic PMSF)
- EDTA: Metalloprotease inhibitor (chelates zinc, calcium)
- Pepstatin A: Aspartyl protease inhibitor
- E-64: Cysteine protease inhibitor
- Complete™/Halt™: Commercial cocktails combining multiple inhibitor classes
