genetic polymorphism of apolipoprotein ( apo ) e is controlled by three common ( epsilon 2 , epsilon 2 , epsilon 4 ) and several rare alleles ( e.g. , epsilon 1 , epsilon 4* , epsilon 4v ) at the apo e structural gene locus and may be demonstrated by isoelectric focusing of delipidated sera followed by immunoblotting .
