Background Information

The apolipoprotein B (ApoB) is a plasma protein synthesized primarily in the liver and intestine and play an important role in lipid and cholesterol metabolism. The ApoB gene encodes two different isoproteins through mRNA editing, ApoB-48 and ApoB-100. ApoB-100 is synthesized exclusively by the liver and is essential for the assembly of VLDL in the liver. ApoB-48 is synthesized exclusively by the small intestine and is essential for the assembly of chylomicrons in the intestine. ApoB-48 and ApoB-100 share a common N-terminal sequence, but ApoB-48 lacks ApoB-100's C-terminal LDL receptor binding region. It is well established that ApoB-100 levels are associated with coronary heart disease. This antibody recognizes both of ApoB-48 and ApoB-100.
