The samples were then vortexted and centrifuged (9600 RCF, 10 minutes). 90 µl of the supernatant was collected and evaporated to dryness. The samples were reconstituted with 40 µl of MeOH/H2O (40%/60%)."},

Mobile phases used for the sample analysis were A: 2mM NH4Ac in H2O:MeOH (70:30) and B: 2mM NH4Ac in MeOH. NH4Ac was used as ionization agent. The samples were kept at 10°C during the whole sample acquisition and 1 µl of the sample volume was injected. The flow rate was set to 0.4 ml/min and the gradient started with 95%A and 5%B with a change after 1.5 minute to 70%A and 30%B, which followed a change after 4.5 minutes to 30%A and 70%B, the last change was after 7.5 minutes with 100%B until the end of run. Gradient program was 18 minutes long. 13 minutes for sample analysis and 5 minutes for clean-up, including equilibration in the end of the run. Maximum pressure limit in the binary pump was set on 850 bar. Dual jet stream electrospray (dual ESI) ion source was used and the ion polarity was on negative mode. The capillary voltage and the nozzle voltage were kept at 4500 V and 1500 V. The N2 pressure was set on 21 psi, with the sheath gas flow as 11 L/min and temperature at 379°C for the nebulizer. The data was acquired with MassHunter B.06.01 software (Agilent Technologies, Santa Clara, CA, The United States of America). MS data processing was performed using open source software MZmine 2.52 (Pluskal et al. 2010)."},
