A broad range, 100X concentrated, ready-to-use protease inhibitor cocktail, Bacterial ProteaseArrest™ inhibits bacterial serine, cysteine and other bacterial specific proteases, including aminopeptidases and aspartic proteases.

• Bacteria specific protease inhibitor cocktail
• 100X concentrated, ready-to-use solution

An optional EDTA solution is provided for enhanced metalloprotease inhibition. It is not present in the actual Bacterial ProteaseArrest™ cocktail as it would inhibit the activity of proteins that require divalent cations (Ca²⁺, Mg²⁺ or Mn²⁺) for their biological activity. In addition, EDTA will inhibit the purification of proteins using immobilised metal affinity chromatography (IMAC).

Applications include inhibition of protease activity in protein preparations of bacterial lysates and protection of proteins from proteolysis in such applications as electrophoresis, purification, storage, and assays.
