Mackay, 12/28/2011, with PE standard is solvent with ammonium acetate using positive-ion mode:
*CID produced only ammonia losses for any normalized collision energy.
*HCD produced ethanolamine losses; nCE at 35% was sufficient. At an isolation window of 1 amu, no fragments were isolated; at 1.5 amu fragments were isolated but spectra were noisy; at 2 amu, fragments were isolated with little noise; at 3 amu, fragments were isolated with no noise.

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
    • LipidXplorer
    • PCA analysis in R
      • Latest is to use the intensities reported by LipidXplorer in R.

For Running Lipid Standards:

  • SOLVENT: chloroform:methanol:2-propanol (2:1:1, v/v/v)
  • IONIZATION AID: 18 mM ammonium acetate

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.
