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 dynamicregulation of cAMP and cGMP signaling. PDE2A, also known as cGMP-stimulatedphosphodiesterase, hydrolyzes cyclic nucleotides cAMP (Km = 2.4 µM) and cGMP, and isinvolved in the regulation of blood pressure and fluid homeostasis. Phosphodiesterases catalyze the hydrolysis of the phosphodiester bond in dye-labeledcyclic monophosphates. Beads selectively bind the phosphate group in the nucleotideproduct. This increases the size of the nucleotide relative to unreacted cyclicmonophosphate. In the polarization assay, dye molecules with absorption transitionvectors parallel to the linearly-polarized excitation light are selectively excited. Dyesattached to the rapidly-rotating cyclic monophosphates will obtain random orientationsand emit light with low polarization. Dyes attached to the slowly-rotating nucleotide-beadcomplexes will not have time to reorient and therefore will emit highly polarized light.
Contraindications: DMSO >1%, strong acids or bases, ionic detergents, high salt
Description: The PDE2A Assay Kit is designed for identification of PDE2A1 inhibitors using fluorescence polarization. The assay is based on the binding of a fluorescent nucleotide monophosphate generated by PDE2A1 to the binding agent. The key to the PDE2A Assay Kit is thespecific binding agent. Using this kit, only two simple steps on a microtiter plate are required for PDE2A1 reactions. First, the fluorescently labeled cAMP is incubated with a sample containing PDE2A1 for 1 hour. Second, 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: 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 96-well format, with purified PDE2A1 enzyme, fluorescently labeled PDE2A1 substrate (cAMP), binding agent, and PDE assay buffer for 100 enzyme reactions.
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: Not applicable (BSL-1)
