Thin-layer chromatography of lipids
 
 

Achieving an optimal separation of lipids by thin-layer chromatography is not always an easy task. In addition to the obvious importance of the materials used (origin of the solvents and silica gel plates), thin-layer chromatographic separations often greatly depend on environmental factors such as room temperature and humidity. You were warned!

 
 
Neutral lipids
 
n-Hexane/ethyl ether/ acetic acid (70:30:1)
 
 
Phosphatidylethanol & phosphatidic acid
 
Upper phase of: ethyl acetate/isooctane/acetic acid/water (130:20:30:100)
