Cathepsin B Human Papain Cysteine Peptidase Enzymatic LeadHunter Assay - TW
OVERVIEW
DOCUMENTS/REFERENCES
Biological Information
Background Information:
Cathepsin B, L and H are lysosomal enzymes that belong to the papain superfamily of cysteine proteinases. They are thought to be involved in tumor invasion and metastasis. In addition, high levels of Cathepsin B have been found in the synovial fluid of rheumatoid arthritis patients which may degrade collagen. Inhibition of Cathepsin B may reduce inflammation, tumor growth and angiogenesis.

Testing Information
Procedure Summary:
Human liver Cathepsin B is used. Test compound and/or vehicle is incubated with 3.94 mU/ml enzyme‡ in modified acetate buffer pH 5.5 for 15 minutes at 25°C. The reaction is initiated by addition of and 20 μM Boc-Leu-Arg-Arg-AMC for another 30 minute incubation period. Determination of the amount of AMC formed is read spectrofluorimetrically at 360 nm/465 nm. Compounds are screened at 10 μM.
Substrate:
20 µM Boc-Leu-Arg-Arg-AMC
