DG as a CETP substrate. A: The CETP-mediated transfer of ³H-DG from phosphatidylcholine-cholesterol liposomes to LDL was measured in the presence of the indicated amount of partially purified human plasma CETP. TP2, a blocking anti-CETP antibody, was combined with CETP and preincubated for 1 h at room temperature prior to addition to the lipid transfer assay. B: CETP was preincubated with or without 1.9 mM thimerosal for 1 h at room temperature before being added to the lipid transfer assay. Values are the mean ± SD (n = 2) and are representative of three similar experiments.
