lipid extraction from isolated pure mitochondria by modified Bligh and Dyer method
lipid quantitation using liquid chromatography-mass spectrometry (LC-MS)
the analysis of phosphatidylinositol (PI) and phosphatidylinositol bisphosphates (PI(3,4)P2 and PI(4,5)P2) by high performance liquid chromatography-mass spectrometry (HPLC-MS)
