Fig. 2.

NDGGE patterns of LpA-I,A-II, LpA-I, and d < 1.20 g/ml fractions isolated from plasma of normal subjects. A. LpA-I,A-II. B. LpA-I. C. d < 1.20 g/ml. All from a female subject. Particle sizes of subpopulations determined at peak maxima are indicated (in nm). Scale at the bottom corresponds to size intervals of major HDL subpopulations identified by NDGGE in plasma of normal subjects. The positions of HDL[1–7] subspecies are indicated by dotted vertical arrows: HDL[5], blue; HDL[4], red; HDL[3], green. Modified from Cheung, et al. (17). D. Densitometry scans of the three lanes in Fig. 1A. T-HDL is black; LpA-I,A-II is blue; and LpA-I is red. The positions of the nine HDL subspecies are indicated with vertical dotted arrows.
