Assay Method Information

Assay Name:  Enzyme Assay
Description:  The aim of this assay is to determine the affinity of a test compound for the mPGES-1 enzyme. 47 ul of recombinant human mPGES-1 (0.5 ug protein/well) containing microsomal suspension in a buffer containing GSH, (2.5 mmol/L L-Glutathione reduced, dissolved in 0.1 mol/L Phosphat Buffer pH 7.4) is dispensed in a 384-well plate and thereafter 1 ul of the test compound(s) is/are added and incubated for 25 minutes at room temperature. The enzyme reaction is started by the addition of 2 ul PGH2 (final conc. 2 uM) dissolved in water-free Diglyme. After 60 seconds the reaction is terminated by addition of a stop solution containing FeCl2 (10 uL 0.074 mol/l FeCl2). The samples are diluted between 1:25 in PBS (Phosphate Buffered Saline). 10 ul of the diluted samples are transferred to 384-well low volume plate.
