Collection:
Collection ID: | CO002325 |
Collection Summary: | The participating women collected stool samples at home or in the delivery hospital. Infant stool samples were collected by the mothers at home and stored in the household freezer (−20°C) until the next visit to the study center. The samples were then shipped on dry ice to the EDIA Core Laboratory in Helsinki, where the samples were stored at −80°C. |

Sampleprep ID: | SP002338 |
Sampleprep Summary: | Stool samples were homogenized in 10 μL of water per milligram stool sample weight using a bead mill (TissueLyser II; Qiagen) and the aqueous homogenates were aliquoted for metabolite profiling analyses. LC-MS samples were prepared for four profiling methods as follows: HILIC-pos: Metabolites were extracted by adding 90 μL of 74.9:24.9:0.2 v/v/v acetonitrile/methanol/formic acid containing stable isotope-labeled internal standards (valine-d8, Isotec; and phenylalanine-d8, Cambridge Isotope Laboratories; Andover, MA) to a 10 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, 4°C) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. C8-pos: Lipids were extracted by adding 190 μL of isopropanol containing 1-dodecanoyl-2-tridecanoyl-sn-glycero-3-phosphocholine as an internal standard (Avanti Polar Lipids; Alabaster, AL) to a 10 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, ambient temperature) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. HILIC-neg: Metabolites were extracted by adding 120 μL of 80% methanol containing inosine-15N4, thymine-d4 and glycocholate-d4 internal standards (Cambridge Isotope Laboratories; Andover, MA) to a 30 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, 4°C) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. C18-neg: Metabolites were extracted by adding 90 μL of methanol containing PGE2-d4 as an internal standard (Cayman Chemical Co.; Ann Arbor, MI) to a 30 μL aliquot of stool homogenate or plasma. Samples were vortexed and then centrifuged (10 min, 9,000 x g, 4°C) to pellet protein precipitates. Supernatants were transferred to glass autosampler vials containing inserts for LC-MS analysis. |
