MS Comments:Samples extracted using Matyash extraction procedure which includes MTBE, MeOH, and H2O. The organic (upper) phase was dried down and submitted for resuspension and injection onto the LC while the aqueous (bottom) phase was dried down and submitted to derivatization for GC. They are resuspended with 110 uL of a solution of 9:1 methanol: toluene and 50 ng/mL CUDA. This is then shaken for 20 seconds, sonicated for 5 minutes at room temperature, and then centrifuged for 2 minutes at 16100 rcf. The samples are then aliquoted into three parts. 33 uL are aliquoted into a vial with a 50 uL glass insert for positive and negative mode lipidomics. The last part is aliquoted into an eppendorf tube to be used as a pool. The samples are then loaded up on an Agilent 1290 Infinity LC stack. The positive and negative mode were run on an Agilent 6530 with a scan range of m/z 120-1200 Da with an acquisition speed of 2 spectra/s. Between 0.5 and 2 uL were injected onto a Waters ACQUITY UPLC CSH C18 1.7um 2.1x100mm Column with VanGuard PreColumn 2.1x5 mm . The gradient used is 0 min 15% (B), 0–2 min 30% (B), 2–2.5 min 48% (B), 2.5–11 min 82% (B), 11–11.5 min 99% (B), 11.5–12 min 99% (B), 12–12.1 min 15% (B), 12.1–15 min 15% (B) with a flow rate of 0.6 mL/min. The mass resolution for the Agilent 6530 is 10,000 for ESI (+).
