| Description: | DGAT activity in membrane preparations was assayed in 50 mM Tris-HCl (pH 7.4), 150 mM MgCl2, 1 mM EDTA and 0.2% BSA, containing 50 μM DAG, 32 μg/ml PC/PS and 8.4 μM [3H]-oleoylCoA (at a specific activity of 30 nCi/well) in a final volume of 50 μl in 384-well format using the red shifted Basic Image FlashPlate™ (Perkin Elmer Cat.No. SMP400). In detail, 10 μl enzyme mix and 10 μl substrate mix were added to 30 μl of assay buffer, optionally in the presence of 1 μl DMSO (blank and controls) or 1 μl of the compound to be tested. This reaction mixture was incubated for 120 minutes at 37° C. and the enzymatic reaction stopped by adding 20 μl of the stop mix. The plates were sealed and the vesicles allowed to settle overnight at room temperature. Plates were centrifuged for 5 minutes at 1500 rpm and measured in Leadseeker. |
