The Mouse PDE7B Assay Kit is designed for identification of inhibitors of Mouse PDE7B using fluorescence polarization. The assay is based on the binding of a fluorescent nucleotide monophosphate generated by Mouse PDE7B to the binding agent. The key to the Mouse PDE7B Assay Kit is the specific binding agent. Using this kit, only two simple steps on a microtiter plate are required for Mouse PDE7B reactions. First, the fluorescently labeled cAMP is incubated with a sample containing Mouse PDE7B 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.
