<p>A novel process of separating from an aqueous medium at least one protein or at least one morphologically organized unit by liquid exclusion chromatography on a solid support previously passivated by treatment with an aqueous solution of a non-proteinic polymer. In this process, the chromatographic support is submitted, prior to the chromatographic operation, to a second passivation consisting in contacting the support with an aqueous solution of a protein which has a molecular weight lower than that of the protein to be separated, and which is adapted to be adsorbed by said support. The support and/or the liquid to be treated are sterilized with antiseptic agent selected from the group constituted by the lower aliphatic halogenated hydrocarbons.</p> |
