Protease Assays & Screening Systems

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.
