Pre-packed reverse phase columns for isolation of complex lipids synthesized from radioactive precursors
DA Figlewicz, CE Nolan, IN Singh and FB Jungalwala
Pre-packed reverse phase columns (Bond Elut) were used for the separation
of complex lipids, such as phosphatidylcholine, cerebrosides, sulfatides,
and gangliosides, from their respective water- soluble radioactive
precursors after their in vitro biosynthesis. After an incubation in vitro,
the entire reaction mixture is passed through the column, where complex
lipids are retained and the hydrophilic radioactive precursors are washed
away from the column. The retained lipids are then eluted with a more
nonpolar organic solvent. The procedure is shown to be simpler and more
efficient than the normally used Folch partitioning method or other
procedures.
