Goat anti Human Apolipoprotein B antibody detects human Apolipoprotein B (ApoB), a large secretory protein with a molecular weight of ~550 kDa that plays a central role in lipoprotein metabolism.
ApoB exists in the plasma in 2 main isoforms, ApoB100 and ApoB48. ApoB100 is synthesised in the liver, and is the major apolipoprotein of very low density, intermediate density and low density lipoproteins (LDL), and is absolutely required for their formation.ApoB100 acts as a ligand for LDL receptors in various cells throughout the body, allowing cells to internalise LDL and absorb cholesterol.
ApoB48 is expressed in the intestine and is present on chylomicrons and their remnants, and lacks the C-terminal LDL-receptor binding region of ApoB100. Elevated plasma concentrations of ApoB containing lipoproteins are key risk factors for the development of atherosclerosis.
