Sampleprep Summary: | The frozen cell preps were defrosted on ice. The samples were extracted using a modified Folch method[1]. 1. Sen, P. et al. Persistent Alterations in Plasma Lipid Profiles Before Introduction of Gluten in the Diet Associated With Progression to Celiac Disease. Clin Transl Gastroenterol 10, 1-10, doi:10.14309/ctg.0000000000000044 (2019). Briefly, 120 µL of cold (4 °C) extraction solvent (CHCl3: MeOH, (2:1 v/v) was added to the samples. The extraction solvent containing the following internal standards: C17 Lactosyl(beta) ceramide (D18:1/17:0, 20 ppb), C17 Glucosyl(beta) ceramide (D18:1/17:0, 20 ppb), C17 ceramide (D18:1/17:0, 20 ppb), C16 ceramide-d7 (d18:1-d7/16:0, 16,57 ppb), C18 ceramide-d7 (d18:1-d7/18:0, 8.75 ppb), C24 ceramide-d7 (d18:1-d7/24:0, 20 ppb), and C24:1 ceramide-d7 (d18:1-d7/24:1(15Z), 9,96 ppb). The samples were the vortexed briefly and left on ice for 30 minutes. The samples were then centrifuged (9400g, 5 min, 4 °C) and then 60 µL of the bottom layer was transfer to a clean mass spectrometry vial (2 mL). The samples were then stored at –80 °C. |
