The proprietary mouse monoclonal antibody 4E6 is developed by professors Holvoet and Collen at the University of Leuven in Belgium. It is is directed against a conformational epitope in the ApoB100 moiety of LDL that is generated as a consequence of substitution of at least 60 lysine residues of Apo B100 with aldehydes (Holvoet 2004). This number of substituted lysines corresponds to the minimal number required for scavenger-mediated uptake of oxidized LDL. Substituting aldehydes can be produced by peroxidation of lipids of LDL, resulting in the generation of oxidized LDL. However, lipid peroxidation is not required. Indeed, aldehydes that are released by endothelial cells under oxidative stress or by activated platelets may also induce the oxidative modification of Apo B100 in the absence of lipid peroxidation of LDL.

The unique affinity of the antibody 4E6 used in the Mercodia Oxidized LDL ELISA makes it possible to measure both MDA and aldehyde modified oxidized LDL, which sets this assay apart from assays based on other antibodies.
