A method for purifying proteins by Protein A chromatography is described which comprises the steps of: (a) adsorbing the protein to Protein A immobilized on a solid phase comprising silica or glass; (b) removing contaminants bound to the solid phase by washing the solid phase with a hydrophobic electrolyte solvent; and (c) recovering the protein from the solid phase.
L'invention porte sur un procédé de purification de protéines par chromatographie de la protéine A, ce procédé consitant à: (a) faire adsorber la protéine par la protéine A immobilisée sur une phase solide comprenant de la silice ou du verre; (b) éliminier les contaminants liés à la phase solide par lavage de cette dernière avec un solvant d'électrolyte; et (c) récupérer la protéine dans la phase solide.
