Functional Assays

Phosphodiesterases (PDEs) play an important role in dynamic regulation of cAMP and cGMP signaling. PDE1C is a calmodulin-dependent PDE that is expressed principally in human myocardium. The key to the PDE1C (Mouse) Assay Kit is the specific binding agent. Using this kit, only two simple steps on a microtiter plate are required for PDE1C reactions. First, the fluorescently labeled cAMP is incubated with a sample containing PDE1C for 1 hour. Second, a binding agent is added to the reaction mix to produce a change in fluorescent polarization that can then be measured using a fluorescence reader equipped for the measurement of fluorescence polarization.

The CD38 Inhibitor Screening Assay Kit (Cyclase Activity) is designed to measure the cyclase activity of CD38 for screening and profiling applications. The CD38 assay kit comes in a convenient 96-well format, with purified recombinant CD38 enzyme, its substrate nicotinamide guanine dinucleotide (NGD+), and CD38 assay buffer for 100 enzyme reactions. In addition, the kit includes the CD38 inhibitor quercitin for use as an inhibitor control.

Bace1 (β-secretase 1) is an aspartic protease that is involved in the processing of the Amyloid precursor protein (APP). Cleavage of APP by BACE1 followed by γ-secretase results in β-amyloid peptide production, which ultimately leads toxic Aβ accumulation. In Alzheimer's disease (AD), it has been widely accepted that Aβ aggregation plays a critical role in AD pathogenesis, suggesting that BACE1 could be a potential target to treat AD. The BACE1 FRET Assay Kit is designed to measure BACE1 activity for screening and profiling applications based on fluorescence resonance energy transfer (FRET) using a labeled peptide substrate (below).

The PCSK9[Biotinylated]-LDLR Binding Assay Kit is designed for screening and profiling purposes. The key to this kit is the high sensitivity of detection of biotin-labeled PCSK9 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, LDLR ectodomain is coated on a 96-well plate. Next, PCSK9 is incubated with LDLR on the plate. Finally, the plate is treated with streptavidin-HRP followed by addition of an HRP substrate to produce chemiluminescence, which can then be measured using a chemiluminescence reader.
