| | hEP2 cAMP Assay |
| Description: | Stock solutions of test compounds are made at a concentration of 10 mM in DMSO, and serially diluted in DMSO to concentrations required for inhibition dose response curves (tested concentration range 30 μM-0.4 nM; 30 μM-0.015 nM or 1 μM-0.01 nM).PGE2 (Cayman 14010, stock solution: 75 μM in DMSO) is used as agonist at 75 nM final concentration, corresponding to EC80.Two point five microliters of diluted compounds are transferred into the assay plate. Plate is pre-incubated 45 minutes at room temperature. Subsequently, 2.5 microliters of PGE2 (final conc. 75 nM) are transferred into the assay plate. Plate is incubated 30 minutes at room temperature. Five μl of each donor (anti-cAMP cryptate) and acceptor (cAMP-d2) are added and the plate is incubated another hour at room temperature in the dark and then read using a BMG LABTECH PHERAstar reader (Excitation: 337 nm, Emission: 620 and 665 nm).The obtained Delta F (fluorescence) values (665 nm/620 nM) are converted into % cAMP values using the measurements of the cAMP calibrator provided in the kit. For each compound concentration the percentage of cAMP compared to DMSO control value as average±STDEV (each concentration is measured in duplicate) is calculated. |
