Protease & Protease Inhibitor Systems
Our Protease & Protease Inhibitor Systems include proteases, protease assays and screening systems, and protease inhibitors. A large variety of mass spectrometry, sequencing grade and general proteases are offered including Proteinase K, a high activity, non-specific serine protease, our partially purified Trypsin for general use and mass spectrometry grade MSG-Trypsin™.
A selection of assays and screening systems for the detection of proteases are also available. We have protease activity assays such as our Protease Screening Kit and Protease Assay Kit. To identify destructive proteases, we offer ProteSEEKER™. We also offer Fluoro™ Protease Assay, a fluorometric, quantitative protease assay. Both resorufin and FITC Casein protease substrates are also available.
A range of protease inhibitor cocktails and individual inhibitors can be found in our protease inhibitor section. ProteaseArrest™ has been proven to inhibit >95% of protease enzyme activity making it 80% more effective than tablet cocktail formats. Superior enzyme inhibition can also be achieved using our dry format inhibitor cocktail, ProteCEASE™.
