| Description: | Microsomes were prepared from COS-1 cells transiently transfected with a plasmid containing human mPGES-1 cDNA, and used as mPGES-1 enzyme. The mPGES-1 enzyme was diluted with a sodium phosphate buffer (pH 7.2) containing reduced glutathione (2.5 mM) and EDTA (1 mM), DMSO or a DMSO solution of a test compound (final concentration of DMSO was 1%) was added to the enzyme, and the mixture was preincubated at 4° C. for 15 minutes. Then, PGH2 as the substrate was added at a final concentration of 1 μM to start the enzymatic reaction, and after incubation at 4° C. for 4 minutes, a solution of ferric chloride (25 mM) and citric acid (50 mM) was added to terminate the enzymatic reaction. Generated PGE2 was measured by using Prostaglandin E2 Express EIA Kit (Cayman Chemical). |
