Application of the solvent density variation method to sedimentation velocity experiments on biologiing. Even if the boundary shows only one apparent step for a bimodal mixture due to diffusion-broadening, the improved method is well able to resolve the density as well as the hydrodynamic radii of both species. This method has been tested on a number of simulated data files as well as on an impure

Allowance for thermodynamic nonideality in the analysis of sedimentation equilibrium distributions rof concentrations commensurate with significant thermodynamic nonideality effects, published data on lysozyme self-association have been analysed to demonstrate the experimental application of the global analysis.

Universal size-independent quantities for the conformational characterization of rigid and flexible iven for three macromolecular structures: (1) ellipsoids, with application to globular proteins, (2) oligomeric arrays of subunits, with seed globulins as examples and (3) flexible-chain macromolecules, illustrated by polystyrene in two solvents.

Calculation of structural parameters from hydrodynamic dataved and predicted values was achieved. Far-reaching conformity between experiments and calculations was also obtained for the prediction of subtle ligand-induced shape changes. A critical assessment of errors reveals the validity of anticipations of structural parameters from hydro-dynamic data. The

Solution properties of supramolecular cobalt coordination arrays of 20–50 mM salt (necessary to obtain ultracentrifuge data not influenced by nonideal sedimentation behavior) again led to aggregation of the material. However, according to equilibrium sedimentation experiments in most solvents the solubilized Co coordination arrays finally were in the form of mon

Working with multidetection in the analytical ultracentrifuge: the benefits of the combination of a y give a deep insight into the colloidal structure of the sample, but can also help to understand the mechanism of the polymerization reaction applied to generate the dispersion under investigation. This can be achieved by thorough sedimentation velocity analysis in both an aqueous and an organic me

Spectroscopic and hydrodynamic investigations of nonionic and zwitterionic detergentsize, on the other, has to be mentioned. Monitoring the sedimentation profiles of weakly absorbing detergents becomes feasible by labeling the detergent micelles using the fluorescent dye .-phenyl-1-naphthylamine. Owing to the chemical nature of the detergents under analysis and differences in size a
