beta-Secretase Detection & Inhibitor Screening Kits

β-Secretase (BACE) is a membrane-bound aspartyl protease that cleaves the amyloid precursor protein and is consequently an excellent target for anti-amyloid therapy in the treatment of Alzheimer's disease. Finding inhibitors of β-secretase is one of the major goals of Alzheimer's disease drug development.

PromoKine's β-Secretase Fluorometric Assay Kit provides a convenient, non-radioactive system for detecting β-Secretase activity in biological samples. The kit provides active β-Secretase as positive control, β-Secretase inhibitor as negative control, optimized peptide substrate (conjugated to two reporter molecules), and buffers for convenient measurement of β-Secretase activity in mammalian samples. β-Secretase inhibitors are also available separately. 

In the β-Secretase Inhibitor Screening Kit, human BACE1 cleaves a quenched substrate, specific for BACE1, generating a product with high fluorescence that can be measured at Ex/Em= 435/500 nm. In the presence of BACE1 Inhibitor (a control is included in this kit), the enzymatic cleavage is impeded.  The assay can be used to screen for new inhibitor compounds. It is high-throughput adaptable and can be completed in less than 1 hour.

Congo Red and DCDAPH can be used to stain Amyloid Protein and Aβ plaques in brain sections.
