The invention relates to a process for making porous cross-linked charged cellulosic polymeric membranes capable of binding to a target molecule. The invention provides methods for separating target molecules from other components in a solution comprising use of membranes obtainable by the process of the invention. The method has particular utility in separating proteins and nucleic acids from cell lysates and cultures.
L'invention concerne un procédé de production de membranes polymères cellulosiques chargées, réticulées et poreuses, pouvant se lier à une molécule cible. L'invention concerne des procédés de séparation de molécules cibles d'autres composants dans une solution faisant appel à l'utilisation de membranes pouvant être obtenues selon le procédé de l'invention. Le procédé est particulièrement utile dans la séparation de protéines et d'acides nucléiques de lysats et de cultures cellulaires.
