Cathepsin B is a cysteine protease that primarily functions as an endopeptidase within endolysosomal compartments in normal cells. High levels of cathepsin B are found in a wide variety of human cancers and in experimental models, such as transgenic models of murine pancreatic and mammary carcinomas, causal roles for this protein have been demonstrated in initiation, growth/tumor cell proliferation, angiogenesis, invasion, and metastasis.
The Cathepsin B Inhibitor Screening Assay Kit is designed to measure the protease activity of Cathepsin B for screening and profiling applications. The Cathepsin B assay kit comes in a convenient 96-well format, with purified Cathepsin B, its fluorogenic substrate, and Cathepsin buffer for 100 enzyme reactions. In addition, the kit includes the cathepsin inhibitor E64 for use as a control inhibitor.

Instructions for use:
See assay kit data sheet for detailed protocol.
Storage / Stability:
Stable at least 6 months from date of receipt, when stored as directed. Kit components require different storage conditions. Be sure to store each component at the proper temperature upon arrival.
Great for studying enzyme kinetics and screening small molecular inhibitors for drug discovery and HTS applications.
