| | Measurement of Inhibitory Effect Against DGAT2 Enzyme Activity |
| Description: | In vitro DGAT2 analysis was performed using a Phospholipid Flash Plate (PerkinElmer) based on the principle of SPA (Scintilation Proximity Assay). First, DGAT2 inhibition compounds serially diluted 5 times from 3 nM to 10 μM (final concentration, 1% DMSO) were mixed in a buffer solution containing 2 μg DGAT2-membrane protein and 20 mM HEPES, 20 mM MgCl2, 1 mg/mL BSA, 50 μM 1,2 sn-oleoyl glycerol (Sigma), put in a 96-well flash plate (FlashPlate) and reacted at 37° C. for 20 minutes, and then 1 μM [14C] ole oil CoA (PerkinElmer, NEC651050UC) was added to be a final volume of 100 μL and further reacted at 37° C. for 15 minutes. After the enzymatic reaction was completed, 100 μL of isopropanol was added, the plate was sealed with a film, and the plate was shaken slowly in a plate shaker. The next day, the amplified scintillation signal (cpm) in Topcounter (Packard) was measured to measure the degree of production of [14C]-labeled triacyl glycerol (TG) as a reaction product. The measured value when the compound was not treated was used as a positive control, and the measured value of the compound treated group was calculated as a relative % to measure the inhibition effect of the compound on TG production. |
