Phosphatase Inhibitor Cocktail solution (cell lysates and tissue extract use incl. samples containing detergents)

Overview

This protease inhibitor cocktail contains a mixture of protease inhibitors with broad specificity for various proteases. It is optimized for use in cell lysates and tissue extracts including samples containing detergents.

Protease inhibitor cocktails protect proteins from degradation by endogenous proteases released during protein extraction and purification.
