Isopycnic Centrifugation of Chromatin in Renografin Solutions
Solutions of Renografin (30-60%) can be centrifuged to form density gradients in the range from 1.0 g/cm(3) to 1.4 g/cm(3) or, alternatively, preformed gradients can be made which under appropriate conditions of centrifugation have an indefinite stability. Such solutions have a low viscosity and a relatively low ionic strength. The density of DNA in such solutions is surprisingly low ( approxim...

متن کاملComplex of DNA with chromatin proteins investigated by isopycnic centrifugation in metrizamide.
Complexes of mouse main band DNA with a fraction of non-histone proteins (NHP), having a high affinity for DNA, in the absence or presence of histones have been investigated by gradient centrifugation in metrizamide. Two types of complexes were formed at an input ratio of NHP to DNA between 1 and 2.5. In metrizamide gradients a majority of DNA was found in the light complex (at the density of 1...
متن کاملAnalysis by isopycnic centrifugation of isolated nucleoids of Escherichia coli.
The isolated, formaldehyde-fixed nucleoid of E. coli has been analyzed by isopycnic centrifugation in CsCl density gradients. The membrane-free nucleoid bands at a density of 1.69 +/- 0.02 g/cm3. The membrane-associated nucleoid bands at a density of 1.46 +/- 0.02 g/cm3. Both species sediment to equilibrium as nearly monodisperse bands in CsCl, suggesting that the nucleoid components of DNA, RN...
متن کاملConcentration and purification of poliovirus by ultrafiltration and isopycnic centrifugation.
A method is described by which poliovirus can be rapidly and simply concentrated by the use of a Diaflo XM-50 ultrafilter membrane. Freon-extracted ultrafilter concentrates banded in CsCl provided a 1,724-fold volumetric concentration of poliovirus. During concentration, trypsin-digested cellular material can pass through the ultrafilter membrane, thus providing a versatile means of degrading a...
