Jordan hinted at his isopycnic explanation in a 1975 paper in Reviews of Geophysics and Space Physics.
RLOs were purified from infected oyster gill tissues by successive differential and isopycnic centrifugations (Wu et al.
Precise and reproducible fractionation of the major HDL particle subpopulations (HDL2b, -2a, -3a, -3b, and -3c) in human plasma is based on an isopycnic equilibrium method developed by Chapman and colleagues (33-36) (Fig.
This process of isopycnic sedimentation at one solute density to separate particles of different densities is called "rho spectrometry" by Price et al.
When the sedimentation coefficients of then-known viruses were plotted against their isopycnic banding densities, nearly all viruses fell into an otherwise essentially vacant area in the center of the plot, surrounded at higher or lower density and higher or lower sedimentation coefficients by various subcellular organelles and macromolecules.
The cell, floating on an isopycnic density gradient in the CPM, also becomes less resistant to stretch.
Moreover, another model wind deficiency was brought out by the divergence of isopycnic trajectories computed with ECMWF analyses at three levels (approximately 1,000, 925, and 850 hPa) from the BLPB trajectories (not shown here).
In these, gradients and samples were caused to flow through rotating seals into a rotor spinning at low speed and then accelerated to maximum speed to effect a separation based on either sedimentation rate or isopycnic banding density (or, in later designs, both).
Lipoproteins were fractionated by isopycnic density gradient ultracentrifugation as described previously (16).
Isopycnic ultracentrifugation was performed on 3-4 mL of plasma by standard methods using KBr at a solvent density of 1.
