This chapter considers ultracentrifugation, which provides methods for the characterisation of the sizes and shapes of macromolecules and macromolecular assemblies. Ultracentrifugation is used in three ways: velocity sedimentation, equilibrium sedimentation, and density-gradient sedimentation.

Centrifugation and Ultracentrifugation
2018INTRODUCTION Biological centrifugation is a process that uses centrifugal force to separate and purify mixtures of biological particles in a liquid medium. The smaller the particles, the higher the g-forces (see next section) required for the separation. It is a key technique for isolating and analysing cells, subcellular fractions,

Advanced high-temperature ultracentrifuge apparatus for mega-gravity materials science
, 2003An ultracentrifuge apparatus, which can generate an ultra-strong gravitational field even >1 000 000 (1 million) G (1 G=9.8 m/s2) over a wide temperature range up to >500 °C with high stability control, was developed for new materials science research ...

Biophysical studies by ultracentrifugation
Current Opinion in Structural Biology, 2001Advances in data analysis are broadening the applicability of ultracentrifugation to the characterization of macromolecular behavior in complex solution. The direct fitting of sedimentation velocity data to the Lamm equation is emerging as a very powerful means to characterize size distributions, improve the precision of data analysis and increase ...
