title: Separation of phosphoinositides and other phospholipids by two-dimensional thin-layer chromatography.
abstract: A simple, rapid, two-dimensional TLC system is presented which resolves the four phosphoinositide cycle phospholipids as well as all commonly encountered major and minor phospholipids. Ca2+-free lipid samples are loaded onto silica gel HL plates and developed first in 48:40:7:5 chloroform:methanol:water:concentrated ammonia, and then in 55:25:5 chloroform:methanol:formic acid. The method was applied successfully to human erythrocytes, human platelets, and BL/VL3 murine lymphoma cells.
