Composition of purified preβ1-HDL

	Concentration (μg/ml)	Mass Ratio (protein:lipid)	Molar Ratio (apoA-1:lipid)e
Protein	22.5 ± 3.5a	—	—
Phospholipid	<0.0899b	100:<0.40	1:<0.11
Cholesterol	<0.0694c	100:<0.31	1:<0.23

^aMean ± SD (n = 4).

^bThe absorbance of each sample was 0.0031, 0.0033, 0.0043, and 0.0033, respectively (mean of duplicates). All values were less than LOD (0.0899 μg/ml).

^cThe absorbance of each sample was 0.0022, 0.0020, 0.0024, and 0.0023, respectively (mean of duplicates). All values were less than LOD (0.0694 μg/ml).

^dThe absorbance of each sample was 0.0023, 0.0044, 0.0022, and 0.0036, respectively (mean of duplicates). All values were less than LOD (0.339 μg/ml).

^eValues are calculated on the basis of the following molecular weights: apoA-1, 28,331 Da; phospholipid, 774 Da; cholesterol, 387 Da; and triglyceride, 886 Da.
