The lipid class composition of the total lipid from the SBT-E1 cells
cultured in medium containing 5% (v/v) FBS is shown in Table 2. The
total lipid consisted of approximately equal proportions of polar and
neutral lipids. Amongst the polar lipids, PC was the most abundant
(26.2% of total lipid) followed by PE (15.1% of total lipid). In terms of
relative abundance, both PC and PE were significantly more abundant
than any of the other polar lipid classes and PC was significantly more
abundant than PE.
