Contents

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)
    • MTBE Extraction [1]
  • 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?
