Interaction of lipoproteins with isolated ovary plasma membranes.

Lipoproteins isolated from plasma membranes of Morris hepatoma 5123.

Interaction of plasma lipoproteins with human platelets.

Human plasma low density lipoproteins (LDL) and high density lipoproteins (HDL) were radioiodinated and their interaction with washed human platelets was assessed. Both ligands were bound by the platelet at 37 degrees C, and an apparent equilibrium was attained within two hours. Minimal binding was observed at 22 degrees C or 4 degrees C. The specificity of these interactions was indicated by t...

The interaction of human plasma glycoaminoglycans with plasma lipoproteins.

Modifications of existing methods have allowed for the isolation and purification of various species of plasma glycosaminoglycans on the basis of their sulfate content and molecular size. All of the preparations precipitated human plasma low density lipoproteins (LDL); maximal precipitation occurred with amounts of glycans corresponding to 50 mug of hexuronate and 12 mg of LDL. The interaction ...

The Interaction of Human Plasma Glycosaminoglycans with Plasma Lipoproteins

Formalinized, tannic acid-treated sheep erythrocytes coated with low density lipoproteins (LDL) or apoprotein B (apo-B) are agglutinated by anti-apo-B immunserum. Those coated with high density lipoproteins (HDL) or apoprotein A-I (apo-A-I) are agglutinated by anti-apo-A-I immunserum. These coated formocells have been used to study the interactions of lipoproteins and apoproteins with plasma gl...

Plasma lipids, lipoproteins and cell membranes.

The major plasma lipids, cholesteryl ester, triacylglycerol, cholesterol and phospholipid, are insoluble in water. They are transported in the circulation as lipoproteins-metabolically diverse macromolecules in which the various lipids are associated with specific polypeptides (the apoproteins). There are four main lipoprotein classes, defined by their size and by the density range within which...
