Technical Information
Apolipoprotein E (ApoE) is a critical apoprotein of the chylomicron which binds to a specific receptor on liver cells and peripheral cells. Defects in ApoE result in disrupted transportation of lipoproteins, fat-soluble vitamins and cholesterol into the lymph systems, and then into blood.
