Ultracentrifugation at moderate pressures

Analytical Biochemistry, 1970
Abstract A pressure chamber was constructed in which analytical centrifuge cells may be filled with nitrogen to pressures of 135 atm. A rise in the schlieren baseline in the gas phase above the solvent permits direct determination of pressure at the conclusion of the experiment.

Exosome enrichment by ultracentrifugation and size exclusion chromatography.

Frontiers in Bioscience, 2018
Exosomes are a subset of extracellular vesicles (EVs) that have important roles in intercellular communication. They contain and carry bioactive molecules within their membranes which are delivered to target cells.

Brightly Luminescent CsPbBr3 Nanocrystals through Ultracentrifugation.

Journal of Physical Chemistry Letters, 2020
Using a combination of density-gradient and analytical ultracentrifugation, we study the photophysical profile of CsPbBr3 nanocrystal (NC) suspensions by separating them into size-resolved fractions.

Ultracentrifugation

2023
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

2018
INTRODUCTION 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,

Proteomics comparison of exosomes from serum and plasma between ultracentrifugation and polymer‐based precipitation kit methods

Electrophoresis, 2019
Exosomes are vesicles with sizes ranging from 30 to 150 nm. The analysis and detection of blood exosomes offers an effective route for cancer diagnosis, prognosis assessment, and therapeutic evaluation of diseases.

Biophysical studies by ultracentrifugation

Current Opinion in Structural Biology, 2001
Advances 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 ...
