the expression of apoe epitopes on isolated apoe and on lipoproteins was probed in competitive microtiter plate immunoassays using the anti-apoe mabs , 125i-labeled apoe as tracer , and isolated apoe , intermediate density ( idl ) , very low density ( vldl1-3 ) , and high density ( hdl2 and hdl3 ) lipoproteins as competitors .
