Ten murine monoclonal antibodies have been produced that are specific for bovine milk lipoprotein lipase. One monoclonal antibody, bLPL-mAb-7, inhibited completely the apolipoprotein C-II (apo-C-II)-dependent enzymic hydrolysis of trioleoylglycerol in a phospholipid-stabilized emulsion, but had no effect on the hydrolysis of the water-soluble substrate p-nitro-phenylacetate. Four times more bLPL-mAb-7 was required to achieve 50% inactivation of lipoprotein lipase activity when the enzyme was preincubated with excess apo-C-II. Disruption of the binding of a dansyl-labeled apo-C-II peptide to lipoprotein lipase by bLPL-mAb-7 was demonstrated by resonance energy transfer, both in the presence and absence of lipid. This antibody thus appears to recognize the apo-C-II binding site of lipoprotein lipase. In addition, bLPL-mAb-7 also inhibited the lipoprotein lipase activity of human post-heparin plasma.

UI MeSH Term Description Entries
D008071 Lipoprotein Lipase An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. The enzyme hydrolyzes triacylglycerols in chylomicrons, very-low-density lipoproteins, low-density lipoproteins, and diacylglycerols. It occurs on capillary endothelial surfaces, especially in mammary, muscle, and adipose tissue. Genetic deficiency of the enzyme causes familial hyperlipoproteinemia Type I.

D009596 Nitrophenols PHENOLS carrying nitro group substituents. Nitrophenol
D004735 Energy Transfer The transfer of energy of a given form among different scales of motion. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed). It includes the transfer of kinetic energy and the transfer of chemical energy. The transfer of chemical energy from one molecule to another depends on proximity of molecules so it is often used as in techniques to measure distance such as the use of FORSTER RESONANCE ENERGY TRANSFER. Transfer, Energy
D006493 Heparin A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
