Effects of Myeloperoxidase-Induced Oxidation on Antiatherogenic Functions of High-Density Lipoprotein

Figure 3

Antioxidant ability of HDL treated with and without MPO. LDL (50 μg protein/mL) was oxidized by 1 μM copper sulfate without (black circle) and with (other symbols) 50 μg protein/mL HDL samples described in Figure 1. (a) Representative oxidation kinetics were obtained by monitoring diene formation at 234 nm at room temperature. (b) Relative lag times are shown (the lag time of LDL alone is defined as 1). Data represent the mean ± SD of three independent experiments. versus LDL.
