[Preparation and characterization of monoclonal antibodies to human apolipoprotein E]

Monoclonal antibodies to human apolipoprotein E (apoE) were prepared and characterized. Antibodies of 3D12F11 clone were shown to be specific to apoE and belong to IgG1 subclass. Dissociation constant of antigen-antibody complex in solution was determined as 3.5 +/- 0.5 nM. The antibodies interacted neither heparin- nor lipid-binding sites of human apoE molecule. The obtained antibodies may be useful for metabolic and structural investigations of apoE as well as for clinical studies.
