Phosphodiesterases (PDEs) play an important role in the dynamic regulation of cAMP and cAMP signaling. Rat PDE1B, also known as calmodulin-dependent phosphodiesterase, is a dual specificity phosphodiesterase has been implicated in allergy, asthma, hypertension, and schizophrenia. PDE1B plays an important role in T cell activation and survival, and that PDE1B-targeted therapy might prove beneficial in leukemias and inflammatory disorders.The Rat PDE1B Assay Kit is designed for identification of inhibitors of Rat PDE1B using fluorescence polarization. The assay is based on the binding of a fluorescent nucleotide monophosphate generated by Rat PDE1B 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 linearlypolarized 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 Rat PDE1B Assay Kit is the specific binding agent. Using this kit, only two simple steps on a microtiter plate are required for Rat PDE1B reactions. First, the fluorescently labeled cAMP is incubated with a sample containing Rat 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 (Rat) ?
