Protease & Protease Inhibitor Systems

Download the Protease & Phosphatase Inhibitors, Enzymes & Assays Hanbook

 

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.

Model:
The Fluoro™ Protease Assay Kit is designed for the quantitative determination of proteases present in a protein sample. The assay uses fluorescein isothiocyanate (FITC)-labeled casein as a general protease substrate. The fluorescein label on the FITC-casein is highly quenched. When the proteas..

Model:
The Protease Assay Kit is designed for the quantitative determination of proteases present in a protein sample, using a dye-labeled protein substrate. The proteases present in the sample of interest will digest the protein substrate and release dye labeled peptides. The absorbance of the dye-labe..

Model:
SG-Chymotrypsin™ is a serine endopeptidase, which predominantly cleaves peptide bonds on the carboxy side of tyrosine, phenylalanine and tryptophan. In addition, chymotrypsin has a low catalytic activity against the carboxy side of leucine, methionine, alanine, aspartic and glutamic acids. It ..

A broad spectrum protease inhibitor cocktail solution that is provided as a 100X concentrated, ready-to-use solution. The cocktail contains a mix of reversible and irreversible inhibitors of serine, cysteine, calpain and metallo- proteases, including Aprotinin, PMSF, Leupeptin, Bestatin and AEBSF.&n..
