Abstract

Le procédé d'isolement de protéines et/ou d'une association de protéines et d'acides nucléiques dans un échantillon comprend les étapes selon lesquelles: on met en contact ledit échantillon et des particules colloïdales magnétiques comprenant un coeur et une enveloppe dans lesquelles: le coeur est magnétique et est enrobé par au moins un polymère comprenant des groupements fonctionnels X choisis parmi les groupements amine, hydroxyle, thiol, aldéhyde, ester, anhydride, chlorure d'acide , carbonate, carbamate, isocyanate et isothiocyanate ou leurs mélanges, dont au moins une fraction a réagi avec d'autres groupements fonctionnels de l'enveloppe, et l'enveloppe est constituée d'un polymère portant des groupements fonctionnels ionisables, Z et Z', identiques ou différents, choisis parmi les groupements amine, acide carboxylique, ester, anhydride, aldéhyde, thiol, disulfure, α-halogénocarbonyle, acide sulfonique, maléimide, isocyanate, et isothiocyanate, qui ont partiellement réagi avec les groupements fonctionnels X du coeur; pour constituer un mélange, on incube ledit mélange sous des conditions prédéterminées, et on sépare du mélange les protéines et/ou les associations de protéines et d'acides nucléiques complexées sur lesdites particules colloïdales par application d'un champ magnétique. L'invention concerne aussi un complexe formé de particules colloïdales et de protéines, un réactif comprenant un tel complexe ou des particules colloïdales.
