We offer a selection of assays to detect and screen for proteases in biological solutions.
Protease Screening Kits are available to screen for the presence of proteases. We also offer  ProteSEEKER™ which allows scientists to identify specific protease types using a panel of protease inhibiotors and a sensitive colorimetric protease assay.

Both colorimetric and flourometric Protease Assay Kits are available. Two Protease Assay Substrates are offered for researchers to design their own assays; a colormetric, resourifin-casein substrate and a fluorometric, FITC-casein substrate. We have Protease Inhibitor Sets to aid in the classification and identification of proteases as well as a wide selection of individual protease inhibitors and inhibitor cocktails.

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..
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-labele..
RESORUFIN-CASEIN PROTEASE SUBSTRATE A colorimetric substrate that when treated with proteases releases resorufin that has an absorbance of 570nm. Supplied lyophilized.   FITC-CASEIN PROTEASE SUBSTRATE A fluorescent (fluorescein isothiocyanate (FITC)) substrate that when treated with p..
Contains 12 ready-to-use individual protease inhibitors for characterization of protease activity.   Each set contains the following protease inhibitors. See individual inhibitors for their specificities and other information.: AEBSF ALLN Antipain, dihydrochloride Aprotini..
Sensitive protease screening is needed to study protease activity present in the sample of interest. The Protease Screening Kit provides you with a simple and quick method for testing your samples for proteolysis. Simply incubate your sample in the reagent provided and obtain results. The screening..
$0.00 provides an interactive version of this protocol where you can discover and share optimizations with the research community.      ProteSEEKER™ identifies specific types of proteases with a panel of twelve protease inhibitors and a sensitive colorimetr..
