Purification of Synechococcus lividus by Equilibrium Centrifugation and Its Synchronization by Differential Centrifugation [PDF]

open access: bronzeJournal of Bacteriology, 1973
A culture of the thermophilic, unicellular, blue-green alga Synechococcus lividus was freed from two thermophilic bacteria by use of equilibrium (isopycnic) centrifugation in Ficoll density gradients. After removal of the bacteria, the alga would grow only on agar plates in a high carbon dioxide atmosphere ...

Reproducibility of Differential Centrifugation Experiments in Tissue Fractionation [PDF]

open access: bronzeNature, 1953
DURING the past few years, differential centrifugation of tissue homogenates has become one of the major techniques of cytology and biochemistry alike. Most of those who have applied this new technique describe the conditions of centrifugation by mentioning only the duration of operation and the centrifugal field prevailing in the middle (or at the ...

FRACTIONATION OF MAMMALIAN LIVER CELLS BY DIFFERENTIAL CENTRIFUGATION [PDF]

open access: hybridJournal of Experimental Medicine, 1946
1. A method is described whereby the major components of liver suspensions are segregated according to size into three main fractions: (a) a large granule fraction composed of elements approximately 0.5 to 2 µ in diameter; (b) a microsome fraction composed of submicroscopic elements approximately 80 to 150 mµ in diameter; and, (c) a supernate fraction ...

Isolation of mitochondria from Saccharomyces cerevisiae using magnetic bead affinity purification. [PDF]

open access: yesPLoS ONE, 2018
Isolated mitochondria are widely used to study the function of the organelle. Typically, mitochondria are prepared using differential centrifugation alone or in conjunction with density gradient ultracentrifugation.

Isolation of Microvesicles from Human Circulating Neutrophils

open access: yesBio-Protocol, 2021
Neutrophil-derived microvesicles (NDMVs) are liberated by neutrophils upon cell activation by molecules. Once activated, neutrophils are primarily involved in acute inflammation; however, the microvesicles they produce are largely anti-inflammatory ...
