Collection:
Collection ID: | CO002545 |
Collection Summary: | human sera were processed by ice-cold methanol. |
Sample Type: | Blood (serum) |
Treatment:
Treatment ID: | TR002564 |
Treatment Summary: | Thawed on ice, 25 µL of serum sample, was mixed with 100 µL extraction solvent of ice-cold methanol containing indole-3-acetic acid-d4 and kynurenic acid-d5. Mixture was vortexed and incubated at −20 °C for 30 min. Following centrifugation at 12,000 × g for 15 min at 4℃, 90 µL supernatant was collected and subsequently evaporated to dryness (Thermo Scientific, Waltham, MA) and dissolved in 45 µL of 10% acetonitrile containing 1 µM chlorpropamide. After centrifugation at 12,000 × g for 15 min at 4℃, supernatants were transferred to autosampler vials for LC-MS analysis. |
Sample Preparation:
Sampleprep ID: | SP002558 |
Sampleprep Summary: | 40 selected trial participants were fed a standardized isocaloric diet (representative of an average American macronutrient intake) to achieve weight maintenance for four weeks At the end of the diet period and following a 12 h fast (and avoidance of over-the-counter medication), serum was collected, stored at -80℃ and subjected to analysis by metabolomics. |
