Background
Phosphodiesterases (PDEs) play an important role in the dynamic regulation of cAMP and cGMP signaling. PDE1B is a calcium-dependent cyclic nucleotide phosphodiesterase that is highly expressed in the striatum. It plays the physiological role in the central nervous system. 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.
Description
The PDE1B Assay Kit is designed for identification of PDE1B inhibitors using fluorescence polarization. The assay is based on the binding of a fluorescent nucleotide monophosphate generated by PDE1B to the binding agent. The key to the PDE1B Assay Kit is the specific binding agent. Using this kit, only two simple steps on a microtiter plate are required for PDE1B reactions. First, the fluorescently labeled cAMP is incubated with a sample containing PDE1B 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 PDE1B?
