Abstract
The present disclosure is directed to a method for separating a biomolecule from a cell culture or from a biological solution, comprising the steps of: (a) providing magnetic particles comprising ligands capable of binding the biomolecule; (b) contacting a cell culture or a biological solution comprising the biomolecule with the magnetic particles to obtain magnetic particles comprising the bound biomolecule; (c) retaining the magnetic particles with a magnetic field in a magnetic separator; (d) optionally washing the magnetic particles with a washing liquid; (e1) providing a flow of an elution liquid through the magnetic separator to elute the bound biomolecule from the magnetic particles while retaining the magnetic particles with the magnetic field in the magnetic separator; (f1) forwarding the biomolecule eluted from the magnetic separator to a membrane chromatography device; (g1) separating the biomolecule from impurities and/or contaminants by membrane chromatography.
