Fig. 3.
Benchtop stability over 4 h (a) and autosampler stability over 45 h (b) of AEA (black bars) and AG (grey bars) in plasma spiked with AEA and 2-AG at 3 ng/mL. Depicted are mean values + SD of total EC concentrations of 3 samples prepared in the same plasma for each time point. AEA, anandamide; AG, arachidonoyl glycerol; EC, endocannabinoid.
