Limits of detection (LOD) and limits of quantification (LOQ).

	Adenosine	Adrenaline	Dopamine	L-DOPA	Noradrenaline	Serotonin
LOD (fmol ± SEM)	9.77 ± 1.20	0.71 ± 0.29	4.64 ± 1.54	43.31 ± 1.04	3.39 ± 0.74	24.04 ± 0.22
LOQ (fmol ± SEM)	32.53 ± 3.99	2.36 ± 0.97	15.46 ± 5.14	144.24 ± 3.45	11.29 ± 2.45	80.05 ± 0.73

Note: LOD was defined as the lowest detectable amount of analyte with a signal-to-noise (S/N) ratio >3. LOQ was defined as the lowest detectable amount of analyte with a signal-to-noise (S/N) ratio >10. Data are presented as the mean ± SEM of five measurements.
