Characterization of HDL subclasses. a Size and shape of particles of the HDL subclasses as viewed with electron microscopy. The mean diameter of the particles of preβ1-HDL (red arrows), HDL-(C), HDL-(B), and HDL-(A) was 5 nm, 7 nm, 9 nm, and 11 nm, respectively. The bar indicates 100 nm. b ApoA-I/cholesterol ratios in 9 separated samples
