Rapid assay of labeled free fatty acids in mixtures of labeled lipids
Journal of Lipid Research, 1968 The fatty acids in lipid mixtures are adsorbed on dehydrated hydroxy-charged ion exchange resin, the other lipids are removed by washing with solvent, and the adsorbed fatty acids are released with quaternary ammonium base for counting. All manipulations
