Cathepsin D, Fluorimetric 390, BioAssay Kit

This kit is optimized to detect Cathepsin D activity. Enhanced Value: It provides enough reagents to perform 100 assays in a 96-well format. High Speed: The entire process can be completed in one hour , Cathepsin D is the lysosomal aspartic proteinase implicated in intracellular protein degradation. It is involved in several pathological processes, such as inflammatory states, atherosclerosis, thrombosis, apoptosis, neoplastic proliferation or Alzheimer disease. , This kit provides a convenient assay for screening of enzyme inhibitors and for continuous assay of Cathepsin D activity using a Mca/Dnp FRET peptide. The sequence of this FRET peptide is derived from the cleavage site of Cathepsin D. In the FRET peptide, the fluorescence of Mca is quenched by Dnp. Upon cleavage into two separate fragments by Cathepsin D, the fluorescence of Mca is recovered, and can be monitored at excitation/emission = 330nm/390nm.
