Sample Preparation:
| Sampleprep ID: | SP001190 |
| Sampleprep Summary: | Samples were removed from the -80°C freezer and allowed to thaw on ice. 225 µL of MeOH with lipid internal standards was added to each sample. Samples were vortexed for 10 seconds. 750 µL of MTBE plus quality controls was added to each sample. Samples were vortexed for 10 seconds. 188 µL of LC-MS grade water was added to each sample. Samples were shaken at 4°C on an orbital mixing plate for 6 minutes. Samples were centrifuged for 2 minutes at 14,000 rcf. 2 aliquots of 350 µL were removed from the top, organic phase. One aliquot was stored at -20°C for backup and the other was dried using a Labconco centrivap. 2 aliquots of 125 µL of the bottom polar phase were removed. One aliquot was stored at -20°C for backup and the other was dried using a Labconco centrivap. |
| Sample Resuspension: | For lipidomics analysis, samples were resuspened in 110 µL of 9:1 methanol:toluene with 50 nM of CUDA as an internal standard. Samples were vortexed for 10 seconds and then sonicated in room temperature water for 5 minutes. Samples were run in a centrifuge for 2 minutes at 16,100 rcf. 100 µL of the supernatant was removed and submited to lipidomics analysis. |
