Separation of Hela Cells by Colloidal Silica Density Gradient Centrifugation
Using a colloidal silica density gradient, HeLa cells in mitosis were found to have a density of 1.040-1.046 g/cc, lighter than the remaining interphase cells. The mitotic cells could be harvested and cultured after centrifugation, showing growth synchrony by measurement of a peak in mitotic index 21 hr after establishing the culture. By using Colcemid or vinblastine sulfate, HeLa cells were ar...
متن کاملPurification of large quantities of influenza virus by density gradient centrifugation.
New zonal centrifuges can conveniently process as much as five orders of magnitude (10(5)) greater sample volumes than conventional swinging-bucket rotors. The continuous-sample-flow-with-banding versions may be used in series with ancillary purification procedures. Here we have studied the combined process: absorption and elution of influenza virus with barium sulfate followed by concentration...
متن کاملDensity gradient centrifugation of rubella virus.
Rubella virus was centrifuged in sucrose density gradients. One of two densities could be ascribed to the virus, depending upon the suspending medium used. The virus was found at a density of 1.16 g/cm(3) after centrifugation for 18 hr in sucrose gradients prepared in distilled water. By contrast, when the sucrose gradients were prepared in tris(hydroxymethyl)aminomethane (Tris)buffer containin...

Neurath, A. Robert (The Wistar Institute, Philadelphia, Pa.), Tadeusz J. Wiktor, and Hilary Koprowski. Density gradient centrifugation studies on rabies virus. J. Bacteriol. 92:102-106. 1966.-Cesium chloride density gradient centrifugation of rabies virus revealed a heterogeneous population of infectious virus particles, the majority of which showed a density of 1.20 g/ml. From results obtained...
متن کاملLymphocytic Choriomeningitis Virus
There has been an upsurge of interest in lymphocytic choriomeningitis virus (LCMV) as a human pathogen and specifically as an underdiagnosed congenital infection (1,2). LCMV is a member of the Arenaviridae family of viruses. Arenaviruses have a complex life cycle involving chronic infection and shedding of the virus in rodents and episodic infections in humans (3,4). Six of the arenaviruses (La...
