Distribution of chromaffin secretory vesicles, acetylcholinesterase, and lysosomal enzymes in sucrose and percoll gradients [PDF]
, 1984 Crude chromaffin secretory vesicles, obtained by differential centrifugation, were further purified on isotonic (Percoll) gradients. The chromaffin vesicle fractions recovered from the gradients contain acetylcholinesterase as well as lysosomal enzymes ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Defining an Optimal Range of Centrifugation Parameters for Canine Semen Processing
Animals, 2023 Our objective was to determine a clinically relevant range of centrifugation parameters for processing canine semen. We hypothesized that higher gravitational (g) force and longer time of centrifugation would result in improved spermatozoa recovery rate (

Laser control of molecular rotation: Expanding the utility of an optical centrifuge [PDF]
, 2019 Since its invention in 1999, optical centrifuge has become a powerful tool for controlling molecular rotation and studying molecular dynamics and molecular properties at extreme levels of rotational excitation. The technique has been applied to a variety of molecular species, from simple linear molecules to symmetric and asymmetric tops, to molecular ...

Controlled enantioselective orientation of chiral molecules with an optical centrifuge [PDF]
Phys. Rev. Lett. 122, 223201 (2019), 2019 We report on the first experimental demonstration of enantioselective rotational control of chiral molecules with a laser field. In our experiments, two enantiomers of propylene oxide are brought to accelerated unidirectional rotation by means of an optical centrifuge.
