Chromatographic analysis in which the stationary phase consists of beads of porous polymeric material sold under the trade name Sephadex; the mobile phase is liquid.

CONT

Gel Filtration Chromatography. The gel filtration method is a relatively new fractionation procedure in liquid chromatography for the separation of molecules according to the differences in size and shape and can be considered a a kind of "molecular sieve." This method has also been referred to in some publications as exclusion chromatography, restricted diffusion chromatography, restricted diffusion chromatography, gel chromatography and gel permeation chromatography, just to mention a few.

OBS

Gel permeation chromatography ... is the preferred term for what has also been known variously as exclusion chromatography, gel chromatography and gel filtration.

English

Subject field(s)
  • Biological Sciences
OBS

(...) it is necessary to pass a sample of the products of the initial extension over a gel filtration column and thus to separate the relatively large extension chains attached to their template from the small individual nucleoside triphosphate building blocks that were not incorporated into new DNA.

French

Domaine(s)
  • Sciences biologiques
OBS

(...) il est d'abord nécessaire de passer un échantillon des premiers produits d'élongation à travers une colonne de gel de filtration, de manière à séparer les chaînes relativement longues et attachées à leur modèle des éléments de base que sont les petits nucléosides triphosphates restant et qui n'ont pas été incorporés dans l'ADN nouvellement synthétisé.
