The chapter discusses the step by step procedure for centrifugation of semen with illustration, and the equipment and supplies needed. It also discusses the necessary conditions for centrifugation of semen.doi:10.1002/9781118904398.ch130Etta A. Bradecamp...
The first analytical ultracentrifuge was designed by Svedberg in the 1920s. Claude and his coworkers developed the concept of preparative centrifugation procedure by making centrifugation techniques principal point of biomedical and biological research for several years. In this present day, centrifugation ...

Rate zonal centrifugation fractionates particles by both size and shape. The procedure is to layer a sample in a restricted zone on top of a pre-poured density gradient. The density gradient is then centrifuged. All particles migrate into the density gradient, because the density gradient has on...

The method by which this volume was determined is described. The procedure itself has no measurable effect on viability or permeability of the cells and permits recovery of about 90% of the cells from the aqueous environment. With this method, it has been found that the intracellular water ...
The resulting supernatant, assayed for thioredoxin reductase by the DTNB reduction procedure (see below), exhibits a specific activity of about 17 times that of the starting supernatant. It is recommended to perform the ammonium sulfate precipitation before heat treatment to obtain a better yield of...
DNA–antibody complexes were isolated by the former procedure from the serum of patients with systemic lupus erythematosus. The sedimentation coefficients of immune complexes varies, however, and rate zonal centrifugation is therefore not an ideal method for preparative work because the complexes will be...
Subsequently, the integrity of the isolation and purification procedure was evaluated by biochemical characterization of marker enzymes of purified peroxisomes and other organelles, such as mitochondria, microsomes, and lysosomes that may be present with purified peroxisomes. Unlike most previous references ...
