RNA was extracted from the SBT-E1 cells incubated with unlabelled
fatty acids (see above) using an RNeasy® Mini kit (Qiagen) according to
the manufacturer's instructions. One microgram of this RNA was then
used to synthesise cDNA using a SuperScript® III first-strand synthesis
kit (Invitrogen) according to the manufacturer's instructions. Any RNA
remaining in the cDNA preparations was digested using Escherichia
coli RNase H and the cDNA was diluted 5-fold in nuclease free water
