Theory of differential centrifugation in angle-head rotors
Analytical Biochemistry, 1969Abstract Differential centrifugation is much used for the isolation and purification of virus. Appropriate conditions of rotor speed, time, number of cycles, etc. are usually chosen empirically. Simple equations are presented here for the prediction of the amount of material that will be recovered in each sedimentation class.

Particle size differentiation in centrifugal force field [PDF]
Nanotechnologies in Russia, 2014 Silicon dioxide nanopowders with various size distributions have been obtained by centrifuge. The distributions of initial and obtained powders have been analyzed by electron microscopy and dynamic light scattering. A potential for effective nanopowder separation in the centrifugal force field using a booster liquid is shown.

Insect Neurosecretory Material Separated by Differential Centrifugation [PDF]
Science, 1962 The factor which accelerates the beating of the insect heart was found to be concentrated in a "large granule" fraction of the corpora cardiaca of the cockroach, Periplaneta americana (L.).

Protein profiling in potato (Solanum tuberosum L.) leaf tissues by differential centrifugation.
Journal of Proteome Research, 2012Foliar diseases, such as late blight, result in serious threats to potato production. As such, potato leaf tissue becomes an important substrate to study biological processes, such as plant defense responses to infection.

An evaluation of the heterogeneity of cytoplasmic particles obtained by differential centrifugation
Biochimica et Biophysica Acta, 1955Abstract 1. 1. As a cell fractionation procedure of the differential fractionation type is continued in order to create new fractions, the degree of heterogeneity of each fraction will increase. Sufficient criteria must be employed to differentiate between fractions.

Large‐scale purification of Qβ‐virus by differential centrifugation
Biotechnology and Bioengineering, 1974AbstractBacterial RNA virus, Qβ, has been purified in gram amounts by differential centrifugation. Final separation of the virus from host E. coli rRNA was based on the density differential in the pellet. The method provided a simplified alternative to the more conventional rate zonal or isopycnic zonal centrifugation techniques.

A method for rapid fractionation of particulate systems by gradient differential centrifugation [PDF]
Experimental Cell Research, 1958 Abstract A method is designed for the rapid fractionation of large volumes of suspensions of particles varying in size and density by gradient differential centrifugation. A centrifuge distribution head is used that permits the rapid construction of continuous liquid density gradients since the gradients are stabilized by centrifugal force as they ...

The Use of Differential Centrifugation in the Study of Tissue Enzymes
1954Publisher Summary This chapter discusses a new technique of differential centrifugation in the study of cellular organization and the theoretical basis of the technique as well as the various factors of a practical nature. The limitations of differential centrifugation become particularly severe when the technique is applied to the study of tissue ...
