Plasma lipoprotein profile was analyzed by FPLC as described 42 (link). Briefly, after 100 μl plasma was injected, lipoproteins were run at 0.5 ml/min in a buffer containing 0.15 M NaCl, 0.01 M Na2HPO4, 0.1 mM EDTA, pH 7.5, and separated on a Superose 6 10/300 GL column (GE Healthcare) by using BioLogic DuoFlow QuadTec 10 System (Bio-Rad, CA). 500 μl of sample per fraction was collected. Triglyceride or cholesterol levels in each fraction were determined using Infinity reagents (Thermo Fisher).
