Fatty acid composition of isolated lipid droplets and young adult
nematodeswas determined by gas chromatography/mass spectrometry
(GC/MS) as previously described [30,31]. Separation of the TAG and
phospholipid fractions used a two-solvent TLC protocol. Lipids were extracted
by adding 5 ml of ice-cold chloroform:methanol (1:1) and incubating
overnight at 20 °C with occasional shaking. A solution of 0.2 M
H3PO4 and 1 M KCl was added to samples, which resulted in phase
separation of the organic and aqueous phase.
