Assay Method Information

Assay Name:  Enzyme Assay
Description:  All compound solutions are made to a concentration of 10 mM in DMSO. To test the stability of the compounds in enzyme assay conditions, 25 nmoles of the compound are incubated in TME buffer with 0.1% BSA (final volume of 250 uL) for 15 minutes at 37 C. Samples (100 uL) are taken at the start of the assay and after 15 minutes, diluted 1:5 with acetonitrile and centrifuged (20,000 RCF, five minutes, room temperature) to precipitate the proteins. The resulting supernatant is injected onto the HPLC. Calculations for determining the percent compound remaining are described in the following equation:% R=Peak Area (T15)/Peak Area (T0)To determine whether or not the compounds are good substrates for FAAH, 25 nmoles of the compound were incubated with 75 ug enzyme preparation in TME buffer with 0.1% BSA (final volume 250 uL). The reaction mixture is treated in the same manner as described above.
