TABLE 1.

Relative lipid composition of exoMel1_ac, exoMel1, and parental cells

Lipids extracted as described under “Experimental Procedures” were stained and quantified by densitometry analysis. The numbers represent the relative amount (%) of each class of lipid with respect to the total identified lipids in the same preparation. Results are the means ± S.D. (n = 3). PS, phosphatidylserine; PI, phosphatidylinositol; PC, phosphatidylcholine; PE, phosphatidylethanolamine.

	SM+GM3	PE	PS+PI+PC	Total

exoMel1ac	29 ± 1a	28 ± 1a	43 ± 1	100
exoMel1	22 ± 1	35.5 ± 2	42.5 ± 1	100
Mel1ac	15 ± 3	38.5 ± 3	46.5 ± 1	100
Mel1	15.5 ± 3	37 ± 4	47.5 ± 1	100
