Basic Protocol
- Get sample from almost any source
- Extraction (both methods use Folch reagent [2:1 chloroform:methanol])
- use Kaluzne method
- trying to implement Bligh & Dyer (gold standard)
- Mass Spectrometry
- ESI-Agilent TOF
- Tandem MS-Q-Star (8-10am)
- Analysis
- Matlab (particular toolbox?) PCA analysis
Main analytes are phosphatidylcholine and phosphatidylethanolamine. Analytes in (-) mode would be phosphatidylserines and phosphatidylethanolamines (which are expected to have stronger signal in - mode). Typical number of analytes?
FAME-GC associated with Craig Thulin and UVU.

This has a great protocol for negative ion mode extraction and analysis on the Orbitrap.
