ProteaseArrest Family
Our ProteaseArrest™ is a highly efficient, liquid format general protease inhibitor cocktail that offers >95% protease inhibition. The ProteaseArrestâ„¢ family of inhibitor cocktails includes other species-specific inhibitor cocktails as well, all of which are enhanced with inhibitors specific for that species. In addition to Bacteria, species-specific cocktails are available for Bacterial, Plant, Yeast, Fungus and Mammalian samples. Our Recom ProteaseArrest™ is designed for recombinant protein purification, particularly 6X His tagged proteins. These proteins are purified by IMAC (Immobilized Metal Affinity Chromatography), which is severely inhibited by the routinely used metalloproteases inhibitor EDTA. Recom ProteaseArrest™ contains a specific bacterial metalloproteases that does not interfere with 6X His protein purification. Our FOCUSâ„¢ ProteaseArrest™ is designed to protect proteins destined for 2D electrophoresis and mass spectrometry analysis.Â
