Binding of ¹²⁵I-apoB from OxLDL to mouse macrophages in the presence of native LDL lipids (■) or OxLDL lipids (●). Elicited mouse macrophages were incubated with native LDL lipid or OxLDL lipid microemulsions for 1.5 h at 4°C. After being washed to remove the unbound lipids, the cells were then incubated with 4 μg/ml of ¹²⁵I-apoB for an additional 1.5 h at 4°C. Binding was quantitated by measuring the (¹²⁵I) radioactivity per mg of cell protein as described in Methods.
