Separation of dog serum lipoproteins by ultracentrifugation, dextran sulfate precipitation, and paper electrophoresis*

Journal of Lipid Research, 1961
The separation of dog serum lipoproteins by ultracentrifugation at a density of 1.063 is hindered by the failure of the high density fraction to accumulate in the bottom portion of the centrifuge tube.
