Sample Preparation:
Sampleprep ID: | SP001861 |
Sampleprep Summary: | Model Mixture Sample Preparation One hundred and four selected chemical standard compounds were purchased from Sigma-Aldrich (St. Louis, MO, USA) and used to prepare stock solutions at a concentration of 0.001 M in LC-MS grade methanol (Fisher Scientific, Pittsburgh, PA, USA). These standards were selected because they map to key metabolic pathways, some involved in cancer. If a chemical could not be completely dissolved in methanol, LC-MS grade water (Fisher Scientific, Pittsburgh, PA, USA) was added to increase solubility. A pooled sample of 104 standard compounds was diluted with methanol at a final concentration of 5 μM. PD1074 C. elegans Bio-mixture Sample Preparation Three 2.0 mm zirconium oxide beads and ~75 μL volume of 0.5 mm glass beads were added to each lyophilized PD1074 C. elegans sample (~10 mg). Samples were placed in a TissueLyser II (QIAGEN, Hilden, Germany) and homogenized at 1,800 rpm, -80 °C for 3 min. One and a half mL of 80% methanol (in water) was added to each homogenized sample. Samples were then shaken using an Isotemp high speed shaker (Fisher Scientific, Pittsburgh, PA, USA) at 1,500 rpm for 30 min, and centrifuged at 22,100 g for 5 min. The supernatant was collected, dried and stored at -80 °C. Prior to MS analysis, dried C. elegans matrices were resuspended with 1 mL LC-MS grade methanol containing the 104 standard compounds at a 5 μM concentration. |

MS Comments: | Samples were analyzed in positive and negative ion modes with direct infusion FT-ICR MS. A spectral size of 8 M was used for data acquisition with an ion accumulation time of 0.025 s and a scan range of 73.71 – 1000.00 m/z. Average scans were set to 200. Raw data files were converted into mzML format using MSConvert. Spectral features were extracted using MZmine 2.51. |
