Sample Preparation:
| Sampleprep ID: | SP002531 |
| Sampleprep Summary: | Samples were prepared following the Emory University Clinical Biomarkers Laboratory SOP for high resolution metabolomics sample preparation. Urine was thawed from -80 °C on ice and vortexed to homogenize. 50 μL urine was transferred to a clean microcentrifuge tube and treated with with 100 μL LC-MS grade acetonitrile containing 2.5 μL internal standard solution. Urine was equilibrated on ice for 30 min. Precipitated proteins were removed by centrifuge (16100 x g at 4 °C for 10 min). 100 μL supernatant was removed and added to an autosampler vial. Samples were maintained at 4 °C until analysis. Samples were prepared alongside NIST SRM 1950 and q3June2014 reference standards. |
