Binding
Radioactive Assay: For all experiments the Phosphodiesterase [3H]cAMP SPA Enzyme Assay (TRKQ7090, GE Healthcare Europe GmbH) were used. The enzymatic activity of the PDE2 and the inhibitory potency of compounds was measured by the conversion of [3H]cAMP to [3H]AMP. [3H]AMP associate to the scintillator soaked yttrium-silicate beads resulting in an increase in scintillation events. Compounds that inhibit the respective enzymes decrease the generation of [3H]AMP and accordingly the number of counts detected.SF9 lysate containing PDE2A is incubated at room temperature for 1 h with [3H]cAMP and the reaction is terminated by addition of SPA beads in 18 mM zinc sulphate. The [3H]AMP bound to SPA beads is determined after at least 3 hours of sedimentation of the beads, the signal is recorded using the TopCount with a recording time of 3 min/well.PDE 2A protein is expressed upon baculovirus infection in SF9 cells. The cells have been incubated upon infection for 3 days and protein production was confirmed.
