Separation of Plasma Lipoproteins

Evaluation of plasma lipids and lipoproteins in patients with psoriasis

Psoriasis is an epidermal disease characterized by chronic relapsing papillon squamous erythematous plaques which may develop in the skin of elbows, knees and extensor surfaces. The cause of psoriasis is unknown. The primary etiologic factor may be related to excessive uncontrolled synthesis is resulting from changes in (1) the function of growth factors ( EGF),(2) presence of proto- oncogenes,...

Isolation of plasma lipoproteins

Lipoproteins were isolated from plasma of man, dog, rabbit, rat, and chicken by ultracentrifugation in continuous density gradients using the B14 titanium and B15 titanium zonal rotors. Both the VLDL and the LDL of human plasma were separated easily from the HDL and from the other more plentiful plasma proteins by centrifugation for only 1 or 2 hr in the B14 or B15 rotor, respectively. Satisfac...

Plasma lipoproteins in fish.

Separation and quantitation of subclasses of human plasma high density lipoproteins by a simple precipitation procedure.

Studies in recent years have suggested that measurement of high density lipoprotein (HDL) subclasses may provide significant information beyond that provided by measurement of total HDL. However, conventional methodology for separation of HDL subclasses involves various types of ultracentrifugation that are time-consuming, costly, and not suitable for many clinical or epidemiological studies. W...

Separation and characterization of plasma lipoproteins of rhesus monkeys (Macaca mulatta).

A group of 14 adult male rhesus monkeys was maintained on a low cholesterol-high fat diet. Periodically, animals were fasted and blood samples were taken for characterization of the plasma lipoproteins. Complete separation of individual plasma lipoprotein classes was not achieved by traditional sequential ultracentrifugation techniques. Rather, initial separation of lipoprotein classes accordin...
