Anti-Apolipoprotein B (Apo B)

Lipids (triglyceride, cholesterol, phospholipids, and cholesteryl esters) are insoluble in plasma. These lipids combine with apolipoproteins to form lipoproteins. This process solubilizes lipids in plasma. Lipoproteins provide a transport system for lipids. They also play an important role in lipoprotein receptor recognition and regulation of certain enzymes in lipoprotein metabolism., Apolipoprotein B plays an essential role in lipid transport and metabolism. Apo B may regulate cholesterol synthesis through its interaction with specific cell membrane receptors and by inhibition of HMG Co A reductase. This enzyme has been identified as the rate controlling enzyme in cholesterol biosynthesis. Apo B may be important in the genesis of atherosclerosis. Apo B is the major protein moiety of all lipoproteins other than high density lipoprotein (HDL) in plasma. Increased levels of apo B100 are associated with an increased risk of coronary artery disease. Apo B exists in human plasma as two isoforms: apo B48 and apo B100. Apo B100 is synthesized in the liver. It is required for the assembly of very low density lipoproteins (VLDL). Applications: Suitable for use in Immunoprecipitation and Western Blot. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher.
