Overview

Protease inhibitors can bind to specific groups in the active centers of protease molecules, reducing or eliminating enzyme activity without denaturing the proteins. This effectively inhibits protein degradation and maintains native protein-protein interactions. Common protease inhibitors include EDTA, E-64, NaVO₃, Bestatin, Leupeptin, Pepstatin A, Aprotinin, etc.

Product Description

The Leupeptin Solution (1 mg/mL) is primarily composed of leupeptin. It is EDTA-free and provided as a concentrated solution. Its working concentration ranges from 1 to 10 μg/mL, with a commonly used concentration of 3 to 5 μg/mL. It is suitable for protein extraction from mammalian tissues and cells, facilitating efficient obtainment of target proteins. The extracted products can be used in subsequent experiments such as Western Blot, Co-Immunoprecipitation (Co-IP), etc.

This reagent is for research use only. Not for use in diagnostic procedures or other purposes.

Procedure (For Reference Only)

  1. Briefly centrifuge the tube before opening to spin down any liquid adhering to the walls or cap.

  2. Add this product to the required volume of Lysis Buffer and dilute to the desired target working concentration (1–10 μg/mL, 3–5 μg/mL recommended) before use

Notes

  1. This product is mildly irritating. Handle with care and avoid repeated freezing and thawing.

  2. For your safety and health, please wear laboratory appropriate attire and disposable gloves while handling reagents.

  3. Use the reagent as soon as possible after opening to ensure optimal performance.
