Sample Preparation:
Sampleprep ID: | SP002342 |
Sampleprep Summary: | For analysis, an aliquot of thawed plasma sample was transferred into a microcentrifuge tube and cold methanol added at 3:1 v/v (i.e., 30 μL sample, add 90 μL cold methanol), vortexed and allowed to sit at –20ºC for two hours. Next, samples were centrifuged at 20,817 x g for 15 min at 4ºC and the supernatant transferred to a new microcentrifuge tube. Usually, the transferred volume was three times that of the original sample (i.e., for a 30 μL sample, add 90 μL cold methanol, then transfer 90 μL supernatant). The samples were dried using a Speed vac at 30 – 40°C and the dried sample stored in a –80ºC freezer for further use or dissolved in solvent for LC-MS/MS analysis. Samples were resuspended in the starting solvent (0.1% formic acid) where the volume was three times the original plasma volume, i.e., 90 μL for 30 μL serum/plasma aliquot. |
