Sampleprep Summary: | The serum samples were mixed with 4-fold volumes of iced acetonitrile, which included 0.001mg/mL 4-chloro-DL-phenylalanine as an internal standard. The mixture was incubated on ice for 15 minutes to facilitate protein removal. Following centrifugation at 20,000 g at 4°C for 10 minutes, the supernatants were carefully collected into new microcentrifuge tubes. After another round of centrifugation under the same conditions, the samples were transferred to sample vials for metabolomics analysis. |
