[Dissociation of low-density lipoprotein complexes with glycosaminoglycans isolated from the human aorta]

It is established that low-density lipoproteins (LDLP) are present in the human vascular wall in the form of complexes with glycosaminoglycans. These complexes dissociate in an electric field and in salt solutions which are usually used for isolating lipoproteins by ultracentrifugation. Besides, in distinction from blood plasma LDL, the LDL of the vascular wall are characterized by a higher flotation rate and asymmetric distribution according to the flotation rate.
