PDE2A Assay Kit

Products from BPS Bioscience require a minimum order value above 400€

Applications: Great for studying enzyme kinetics and screening small molecular inhibitors for drug discovery and HTS applications.

Background: Phosphodiesterases (PDEs) play an important role in the dynamic regulationof cAMP and cAMP signaling. PDE2A, also known as cAMP-stimulated phosphodiesterase,hydrolyzes cyclic nucleotides cAMP (Km = 2.4µM) and cAMP, and is involved in the regulationof blood pressure and fluid homeostasis.

Description: The PDE2A Assay Kit is designed for identification of PDE2A inhibitors using fluorescence polarization.The assay is based on the binding of a fluorescent nucleotide monophosphate generated by PDE2A to the binding agent. PDE2A catalyzes the hydrolysis of the phosphodiester bond in dye-labeled cyclic adenosine monophosphate (cAMP). Nanoparticle beads selectively bind the phosphate group in the nucleotide product. This increases the size of the nucleotide relative to unreacted cAMP. Since the degree of polarization of a fluorophore is inversely related to its molecular rotation, dyes attached to the slowly-rotating nucleotide-bead complexes will not have time to reorient and therefore will emit highly polarized light. Conversely, dyes attached to the rapidly-rotating cyclic monophosphates will obtainrandom orientations and emit light with low polarization. The key to the PDE2A Assay Kit is the specific binding agent. Using this kit, only two simple steps on a microtiter plate are required for PDE2A reactions. First, the fluorescently labeled cAMP is incubated with a sample containing PDE2A1 for 1 hour. Second, a binding agent is added to the reaction mix to produce a change in fluorescent polarization. The FP signal is measured using a fluorescent microplate reader capable of measuring fluorescence polarization.

Storage Stability: Stable at least 6 months from date of receipt, when stored as directed. Kit components require different storage conditions. Be sure to store each component at the proper temperature upon arrival

Supplied As: The PDE2A inhibitor screening assay kit comes in a convenient 384-well format, including purified PDE2A1 enzyme, fluorescently labeled PDE2A substrate (cAMP), binding agent, and PDE assay buffer for 384 enzyme reactions.

Warnings: Avoid freeze/thaw cycles.

Biosafety Level: Not applicable (BSL-1)
