Enzymes & Protease Inhibitors

Active enzymes and inhibitors—with the data to back them up.

Whether you're developing enzyme-based diagnostics, studying protease activity in disease models, or characterizing inhibitor function, your results depend on consistent, measurable activity.

Athens enzymes and protease inhibitors are purified in-house, with activity reported for every lot.

From myeloperoxidase and cathepsins to alpha-1 antitrypsin and alpha-2 macroglobulin, our proteins support IVD development, disease research, and functional assays.

Experience the Athens Standard:

  • Lot-specific activity and purity data
  • Frozen and lyophilized formats
  • Scalable to production quantities
  • >95% of retail products ship next-day

Consistent activity. Documented results. Batch after batch.
