Patent

CA 2400722

The invention relates to an anion exchanger resin, to the use thereof as a polymeric anion exchanger in chromatographic methods, especially for cleaning and isolating nucleic acids, and to a chromatographic method, especially for cleaning and isolating nucleic acids. The invention also relates to a method for producing the anion exchanger resin. Said anion exchanger resin can be obtained by polymerizing at least one acrylic acid derivative with at least one cross-linking agent. The acrylic acid derivative is represented in general formula (I), and the cross-linking agent used during polymerization is described by general formula (III).

L'invention concerne une résine échangeuse d'anions, son utilisation comme échangeur polymère d'anions dans des procédés chromatographiques, notamment pour purifier et isoler des acides nucléiques. L'invention concerne également un procédé chromatographique, notamment pour purifier et isoler des acides nucléiques. L'invention concerne par ailleurs un procédé permettant de produire cette résine échangeuse d'anions. Cette résine échangeuse d'anions s'obtient par polymérisation d'au moins un dérivé d'acide acrylique avec au moins un agent de réticulation. Le dérivé d'acide acrylique présente la formule générale (I) et l'agent de réticulation utilisé pendant la polymérisation est décrit par la formule générale (III).
