EL-NYMC-154-Run 4 | SA086430 | FL012866 | Early Disseminated Lyme | Sample Type |
Collection:
Collection ID: | CO001284 |
Collection Summary: | Sera from early Lyme disease patients were collected pretreatment at the initial visit to the clinic. Healthy control serum donors were from endemic and non-endemic regions for Lyme disease. |
Sample Type: | Blood (serum) |
Treatment:
Treatment ID: | TR001305 |
Treatment Summary: | N/A |
Sample Preparation:
Sampleprep ID: | SP001298 |
Sampleprep Summary: | Small molecule metabolites were extracted from sera and analyzed by LC-MS as previously described. Specifically, cold methanol (60 µl) was added to 20 µl of sera, vortexed and incubated at -20°C for 1 h. Samples were warmed to room temperature for ten minutes, vortexed and centrifuged at 18,000 x g for 30 min. The supernatant (65 µl) was transferred to a new microcentrifuge tube and dried under vacuum. The dried metabolite extract was suspended in 50% methanol (40 µl) centrifuged at 18,000 x g for 15 min. An aliquot (35 µl) was transferred to an autosampler vial for LC-MS analysis. |
