Jordan hinted at his isopycnic explanation in a 1975 paper in Reviews of Geophysics and Space Physics.
It is not at all clear that the isopycnic hypothesis in full will stand the test of time.
RLOs were purified from infected oyster gill tissues by successive differential and isopycnic centrifugations (Wu et al.
As an initial step toward assessment of this hypothesis, plasma HDL from normolipidemic individuals was subfractionated by isopycnic density gradient ultracentrifugation into 5 subfractions (Fig.
On the basis of these findings, it may be concluded that: (a) the detected protein clusters described herein are potentially indicative of distinct subspecies of HDL particles that display specific biological function(s); (b) the proteomic analyses of defined HDL subspecies isolated by isopycnic density gradient ultracentrifugation from normolipidemic plasma samples have identified small dense HDL3c as a distinct particle subset(s); and (c) specific lipid and protein components of HDL3c endow them with potent antioxidative activities.
Automatic sorting of zooplankton by isopycnic sedimentation in gradients of silica: performance of "rho spectrometer.
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.
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.
