density gradient
1Density gradient — is a spatial variation in density over an area. The term is used in the natural sciences to describe varying density of matter, but can apply to any quantity whose density can be measured. [1] [2] Contents 1 Aerodynamics 2 …
2density gradient centrifugation — noun (biology) The separation of cells, cell components or complex molecules on the basis of their density differences by centrifuging them to their density equilibrium positions in gradients established in appropriate solutions • • • Main Entry …
3density gradient centrifugation — density gradient centrifugation. См. центрифугирование в градиенте плотности. (Источник: «Англо русский толковый словарь генетических терминов». Арефьев В.А., Лисовенко Л.А., Москва: Изд во ВНИРО, 1995 г.) …
4density gradient centrifugation — High speed centrifugation in which molecules are separated on the basis of their different densities using a concentration gradient of caesium chloride or sucrose. The density gradient may either be formed before centrifugation by mixing two… …
5density gradient — A column of liquid in which the density varies continually with position, usually as a consequence of variation of concentration of a solute. Such gradients may be established by progressive mixing of solutions of different density (as for… …
6density gradient — progressive variation in density over a distance; used particularly for that of a solute along the height or width of a confined solution; see also under centrifugation …
7density gradient centrifugation — ultracentrifugation in a liquid, such as cesium chloride solution, the density of which increases along the lines of centrifugal force, the substances under test or preparation seeking their level of density …
