Cyclic nucleotide phosphodiesterases (PDEs) hydrolyze the secondary messengers cyclic AMP (cAMP) and cyclic GMP (cGMP) at their 3'-phosphodiester bond, to yield 5'-adenosine
monophosphate (5'AMP or AMP) and 5'-guanosine monophosphate (5'GMP or GMP) respectively. These secondary messengers maintain homeostasis and thu s play a pivotal role in
regulating cellular pathways.
While inhibition of this class of enzymes has had clinical success, a major challenge in designing inhibitors that specifically inhibit PDE subtypes has been the sequence conservation of the
catalytic domain among PDE subfamilies. Thus, new methods that can prospect into the structure and the functional properties of conformational variants of PDEs are urgently needed, as the
success of PDE inhibitors will depend upon such characterization. The development of a robust enrichment method would be a crucial first step for drug discovery and biomarker classification
within the PDE class. However, classical substrate affinity methods have not evolved because of the instability of the cyclic phospho-ester bond. PDEnRich™ is a new reagent kit used for
the enrichment and isolation of cyclic AMP (cAMP) and cyclic GMP (cGMP) phosphodiesterases.
PDEnRich™ was discovered upon screening a silica-based, multi-dimensional surface library and optimized for the enrichment of phosphodiesterase activity*. The standard prep protocol starts
with 100 µl of tissue/cell extracts, or approximately 0.5 mg total protein, but the process can be scaled up or down to accommodate different sample volumes and protein concentrations. The kit i
ncludes all necessary reagents for immediate use.
