Product Overview :
Phosphodiesterases (PDEs) play an important role in dynamic regulation of cAMP and cGMP signaling. PDE3A, also known as cGMP-inhibited phosphodiesterase, has been implicated in cardiovascular function and fertility. The assay is based on the generation of FAM-labeled nucleotide monophosphates by the phosphodiesterase. These phosphate groups bind to terbium-labeled nanoparticles, resulting in energy transfer from the terbium to the FAM, which emits a fluorescent signal at 520 nm. The change in fluorescent intensity can be easily measured using a fluorescence plate reader.
Description :
The PDE3A TR-FRET Assay Kit is designed for identification of inhibitors of PDE3A using TR-FRET (Time Resolved Fluorescence Resonance Energy Transfer) technology. Using this kit, only two simple steps on a microtiter plate are required for the PDE3A activity assay. First, the fluorescent-labeled cAMP is incubated with a sample containing PDE3A for 1 hour. Second, a binding agent and a terbium donor are added to the reaction mix and incubated for 1 hour. Then, fluorescence intensity can be measured using a fluorescence reader.
Applications :
Great for studying enzyme kinetics and screening small molecular inhibitors for drug discovery and HTS applications.
Storage :
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.
