| | Phosphodiesterase (PDE) 2A and 10 Assay |
| Description: | All reactions were performed in 384 well plates, Perkin Elmer black optiplates and IMAP reaction buffer with 0.1% Tween20 (kit component)Compounds were serial diluted in DMSO. With an intermediate dilution step with reaction buffer DMSO concentration was reduced to achieve 1% DMSO in the assay reaction. Setup of the assay started with 10 μl enzyme ( 10 ng/well, depending on prep. batch), 5 μl compound, reaction was started by addition of 5 μl labeled cAMP (30 nM, final concentration), immediately mixed for 15 seconds on a Eppendorf mixmate (2000 rpm) followed by an incubation at room temperature for 90 minutes in the dark. Reaction is stopped by adding of 60 μl binding buffer for FP/cAMP (kit component). After at least 90 min of further incubation (room temperature, dark) the assay was measured at 485 nm excitation/525 nm emission in an Envision multilabel reader (PerkinElmer).Each assay plate contained wells with vehicle controls (1% DMSO) for the measurement of non-inhibited reaction (=100% control) and wells without enzyme as 0% controls.The analysis of the data was performed by calculation of the percentage of inhibition in the presence of test compound compared to the vehicle control samples (100% control, no inhibition) and a low control (0% control, no enzyme). |
