Collection:
| Collection ID: | CO001586 |
| Collection Summary: | Peripheral blood samples were collected in Serum Separator Tubes (SST). Serum samples were isolated on site in Burkina Faso by centrifuging blood samples in SST tubes for 30 minutes at 1500 RCF. Separated serum aliquots of 0.5 ml were transferred to cryovials and stored at -80°C. |
| Sample Type: | Blood (serum) |
| Storage Conditions: | -80℃ |
| Collection Vials: | Serum Separator Tubes (SST) |
| Storage Vials: | cryovials |
Treatment:
| Treatment ID: | TR001606 |
| Treatment Summary: | No treatment was done to any of the samples prior to profiling |
Sample Preparation:
| Sampleprep ID: | SP001599 |
| Sampleprep Summary: | Samples were prepared using the automated MicroLab STAR® system from Hamilton Company. Several recovery standards were added prior to the first step in the extraction process for QC purposes. To remove protein, dissociate small molecules bound to protein or trapped in the precipitated protein matrix, and to recover chemically diverse metabolites, proteins were precipitated with methanol under vigorous shaking for 2 min (Glen Mills GenoGrinder 2000) followed by centrifugation. The resulting extract was divided into five fractions: two for analysis by two separate reverse phase (RP)/UPLC-MS/MS methods with positive ion mode electrospray ionization (ESI), one for analysis by RP/UPLC-MS/MS with negative ion mode ESI, one for analysis by HILIC/UPLC-MS/MS with negative ion mode ESI, and one sample was reserved for backup. Samples were placed briefly on a TurboVap® (Zymark) to remove the organic solvent. The sample extracts were stored overnight under nitrogen before preparation for analysis. |
