Phosphodiesterases (PDEs) play an important role in the dynamic regulation of cAMP and cAMP signaling. Dog PDE3A, also known as cGMP-inhibited phosphodiesterase, has been implicated in cardiovascular function and fertility. The Dog PDE3A Assay Kit is designed for identification of inhibitors of canine PDE3A using fluorescence polarization. The assay is based on the binding of a fluorescent nucleotide monophosphate generated by Dog PDE3A to the binding agent.Phosphodiesterases catalyze the hydrolysis of the phosphodiester bond in dye-labeled cyclic monophosphates. Beads selectively bind the phosphate group in the nucleotide product. This increases the size of the nucleotide relative to unreacted cyclic monophosphate. In the polarization assay, dye molecules with absorption transition vectors parallel to the linearly-polarized excitation light are selectively excited. Dyes attached to the rapidly-rotating cyclic monophosphates will obtain random orientations and emit light with low polarization. Dyes attached to the slowly-rotating nucleotide-bead complexes will not have time to reorient and therefore will emit highly polarized light.The key to the Dog PDE3A Assay Kit is the specific binding agent. Using this kit, only two simple steps on a microtiter plate are required for Dog PDE3A reactions. First, the fluorescently labeled cAMP is incubated with a sample containing Dog PDE3A 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.Need us to run inhibitor screens or profile your compounds against PDE3A (Dog) ?
