Immobilized capillary tyrosinase microreactor for inhibitor screening in natural extracts by capillary electrophoresis

- A method for preparing in-column tyrosinase microreactor based on LBL approach was developed for screening enzyme inhibitors.
- Tyrosinase was immobilized on the surface of capillary via ionic binding technique with cationic polyelectrolyte HDB.
- The method displays advantages including very low cost and reusable enzyme.
- Inhibitors in natural extracts were screening by the present method.
