Zonal centrifugation in reorienting density gradients
Biochimica et Biophysica Acta (BBA) - General Subjects, 1971Abstract 1. 1. Zonal rotors which do not require rotating-seal assemblies were tested and employed for quantitative cell fractionations in sucrose density gradients. The design and operation of these rotors represents a departure from other zonal rotors presently in use.

Density-Gradient Centrifugation
1998In some cases, further separation of virus from the plant contaminants can be achieved by placing the clarified extract on top of a small volume of a sucrose solution in a centrifuge tube, the so-called sucrose cushion. Although the higher viscosity of the sucrose solution delays the virions reaching the bottom, the plant contaminants may be slowed ...

Computer Simulation of Density-Gradient Centrifugation
1979Modern biochemical techniques are continuously refined to produce new and improved results. Improvements in the useful power of a biochemical technique can in principle be achieved in two ways. One is the classic trial-and-error approach whereby the parameters of the experimental conditions are varied one by one until a suitable set of conditions is ...

Density gradient centrifugation in angle-head rotors
Analytical Biochemistry, 1964Abstract By utilizing DNA and T3 bacteriophage as test materials, good isopyenic banding in CsCl was obtained in #30 and #40 Spinco fixed-angle rotors. Values for the buoyant densities of the materials tested agree with published values and density gradients formed after prolonged centrifugation approximate the calculated compositional gradient at ...

Separation of nanorods by density gradient centrifugation
Journal of Chromatography A, 2011The experimental conditions necessary for the synthesis of well-defined nanoparticles are often difficult to control. There is thus a compelling need for post-synthesis separation of nanoparticles polydispersed in size and shape. We demonstrate here both theoretically and experimentally that gold nanorods with diverse aspect ratios can be separated ...

Enucleation of cells by density gradient centrifugation
Experimental Cell Research, 1975Abstract HEp-2 cells can be enucleated by ultracentrifugation in a colloidal silica (PTL) density gradient, containing cytochalasin B. Under optimal conditions, more than 70% of the cells are enucleated. Purification up to 97% is carried out by centrifugation at low speed through a second, preformed PTL density gradient.

Zonal separations by density-gradient centrifugation
Archives of Biochemistry and Biophysics, 1953Summary Zonal separations in the centrifuge have been obtained by floating a layer of a solution of particles on a second solution which has a density gradient and in which the particles are soluble. During subsequent centrifugation all those particles of the same size, shape, and density sedimented as a zone.

Plant Protoplast Enucleation by Density Gradient Centrifugation
2003A number of different methods have been developed for the enucleation of cells, particularly mammalian cells. Centrifugation of cells adhering to a surface may lead to the nucleus being drawn out from the cytoplasm, resulting in the formation of an enucleated cell or cytoplast and a nucleus surrounded by a thin layer of cytoplasm bounded by a plasma ...
