Assay Method Information

Assay Name:  In Vitro Competitive Activity-Based Protein Profiling
Description:  Proteomes (mouse brain membrane fraction or cell lysates) (50 μL, 1.0 mg/mL total protein concentration) were preincubated with varying concentrations of inhibitors at 37° C. After 30 min, FP Rh (1.0 μL, 50 μM in DMSO) was added and the mixture was incubated for another 30 min at 37° C. Reactions were quenched with SDS loading buffer (50 μL-4×) and run on SDS-PAGE. Following gel imaging, serine hydrolase activity was determined by measuring fluorescent intensity of gel bands corresponding to MAGL, ABHD6 and FAAH using ImageJ 1.43u software. Data from this assay is shown in Table 2 (% inhibition at 1 μM).
