Sample Preparation:
| Sampleprep ID: | SP001193 |
| Sampleprep Summary: | Briefly, before SPE cleanup, the frozen samples were removed from the freezer and centrifuged at 14,000 RPM at 4°C for 10 minutes. The supernatant was removed, transferred to a new microcentrifuge tube, and spiked with 10 μL of 10 pg/μL internal standard solution (100 pg of each: 5(S)-HETE-d8, 8-iso-PGF2a-d4, 9(S)-HODE-d4, LTB4-d4, LTD4-d5, LTE4-d5, PGE2-d4, PGF2a-d9 and RvD2-d5 in ethanol). The supernatant was dried in a vacuum centrifuge and reconstituted with 1.0 mL of 10% methanol. The reconstituted extracts were loaded on a Strata-X 33 μm 30 mg/1maL SPE column (Phenomenex, Torrance, California, USA) preconditioned with 1.0 mL of methanol followed by 1.0 mL of water. The SPE column was washed with 10% methanol and then eluted directly into a reduced surface activity/maximum recovery glass autosampler vial with 1.0 mL of methyl formate. The methyl formate was evaporated completely from the vial with a stream of nitrogen and the SPE cartridge was then eluted with 1.0 mL of methanol directly into the same autosampler vial. The methanol was evaporated to dryness with a stream of nitrogen and the sample was reconstituted with 20 uL of ethanol. The samples were analyzed immediately or frozen at -70 °C until analysis. |
