ApoB-100 is the largest of the apoB group of proteins, consisting of 4563 amino acids. ApoB100 is found in lipoproteins originating from the liver (VLDL, IDL, LDL). Importantly, there is one ApoB100 molecule per hepatic-derived lipoprotein. ApoB48 and ApoB100 share a common N-terminal sequence, but ApoB48 lacks ApoB100’s C-terminal LDL receptor binding region. In fact, ApoB48 is so called because it constitutes 48% of the sequence for ApoB100.ApoB 48 is a unique protein to chylomicrons from the small intestine. After most of the lipids in the chylomicron have been absorbed, ApoB48 returns to the liver as part of the chylomicron remnant, where it is endocytosed and degraded.
It is well established that ApoB100 levels are associated with coronary heart disease, and are even a better predictor of it than is LDL level. A naive way of explaining this observation is to use the idea that ApoB100 reflects lipoprotein particle number (independent of their cholesterol content). In this way, one can infer that the number of ApoB100-containing lipoprotein particles is a determinant of atherosclerosis and heart disease.
The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.
