Abstract[English]
The present invention relates to methods of viral inactivation with a mixture of solvent and detergent. In particular, the present invention is directed to a method for preparing a virus- inactivated polypeptide solution wherein a polypeptide material is first loaded into an affinity chromatography column then incubated with said mixture of a solvent and a detergent within the affinity chromatography column.[French]
La présente invention concerne des procédés d'inactivation virale avec un mélange de solvant et de détergent. En particulier, la présente invention concerne un procédé de préparation d'une solution polypeptidique inactivée par un virus dans laquelle une substance polypeptidique est d'abord chargée dans une colonne de chromatographie d'affinité puis incubée avec ledit mélange de solvant et de détergent dans la colonne de chromatographie d'affinité.
