From this experiment, we decided that 2 M itraconazole was able to activate AMPK to 70% of the maximum achievable response induced by 20 mM 2DG. The specificity of the FRET reporter response was confirmed by using a version of the reporter made up of a T/A mutation in the phosphorylation motif rendering it insensitive to AMPK activation; as expected, neither itraconazole nor 2DG induced any changes in the emission ratio of the mutated reporter (test. *< 0.05, ***< 0.001.
