The sedimentation constant of an infectious component in ribonucleic acid preparations from foot-and-mouth disease virus has been determined by density-gradient ...

Phytochrome, cross linked in situ to its receptor by glutaraldehyde fixation, and radioactively-labelled membrane material, obtained by lactoperoxidase-catalysed 125I-treatment of maize coleoptiles ...

Density gradient centrifugation is an effective method for the isolation and purification of small particles. Hollow rotors capable of hosting density gradients replace the need for centrifuge tubes ...

Definition: A method where the components of a sample are separated on the basis of their density, in a density gradient of e.g. CsCl in a centrifuge, according to buoyant density. The species in the ...

Enrichment of leukocytes from blood products like buffy coat, leukocyte reduction chambers (LRSC) or leukapheresis material can be time consuming and could influence the physiology of the target cells ...
