PDE10A2 Assay Kit

The PDE10A2 Assay Kit is a fluorescence polarization (FP), homogeneous, 96-well assay kit designed for the screening and profiling of PDE10A2 (Phosphodiesterase 10A2) inhibitors. This assay takes advantage of a specific fluorescent phosphate-binding nanoparticle. The kit contains enough purified recombinant PDE10A2, fluorescent probe, PDE assay buffer, Binding Agent, and diluent for 100 reactions.Figure 1: Illustration of the PDE10A2 Assay Kit principle.The assay uses a fluorescein-labeled cyclic adenosine monophosphate (cAMP-FAM for PDE10A2), in which the phosphate group is engaged within the cyclic nucleotide. This is a very small molecule that rotates fast (low FP) . PDE10A2 catalyzes the hydrolysis of the phosphodiester bond in the cyclic nucleotide and frees the phosphate group. In a second step the free phosphate group is recognized by a specific phosphate-binding nanobead (Binding Agent) leading to the formation of a large complex, with restricted movement (high FP) . FP is proportional to PDE10A2 activity.This assay requires a fluorescent microplate reader capable of measuring fluorescence polarization (FP) and equipped with the required parts to read the FP signal.
