Sample Preparation:
Sampleprep ID: | SP000923 |
Sampleprep Summary: | The retrospective serum samples (80 microliters[ul]) were incubated with 3 volumes of cold methanol (100%) for 1 hour at -20C. After this incubation, the samples were centrifuged for 30 minutes at 18,000 xg at 4C to clear the supernatant. The supernatant was then transferred and dried under vacuum. Samples were re-suspended in 80 μl of 50% methanol. Prior to the injections on the LC-MS instrument, the samples were centrifuged for 30 minutes at 18,000 xg at 4oC. |
