Analytical Equilibrium Density Gradient Ultracentrifugation of Human Plasma Lipoproteins

Abstract

Meselson, Stahl and Vinograd1 first described the equilibrium density gradient technique for the examination of DNA in the analytical ultracentrifuge, and the technique has since been used to investigate a number of macromolecules2. In the past, density gradient investigations of lipoproteins have been limited to the preparative ultracentrifuge. This communication reports the banding of human plasma lipoproteins in sucrose–sodium bromide density gradients at equilibrium in the analytical ultracentrifuge.
