Abstract
This protocol details how to perform lipid extraction using a methyl tert-butyl ether (MTBE)-based extraction method compatible with mass spectrometry.
Lipid Extraction
Add 200 µL of cold methanol and 800 µL of cold methyl tert-butyl ether (MTBE) to the samples.
Vortex.
Add 200 µL of water. Phase separation into aqueous and organic phases should occur.
Centrifuge the extraction mixture at 10000 x g, 4°C, 00:10:00 to separate the organic and the aqueous phases.
10m
Collect the upper organic phase.
Dry it in a SpeedVac and store at -80 °C until analysis.
For mass spectrometry analysis, reconstitute the samples with 20 µL -40 µL of acetonitrile/isopropanol/water in a 65:30:5 ratio (v/v/v).
Note
For LC-MS measurement, a C8 column (Luna 3u, 2 x 100 mm, 3.0 µm, Phenomenex) is recommended. DMPC gets stuck in the C18 column.
