Abstract

We explored the feasibility of attaching charged tails to a target protein, in this case β-galactosidase, for selective recovery. In this process, an ion-exchange membrane was used for selective binding and release of β-galactosidase with the attached purification fusions. Strength of binding and purity of eluate increased with increasing tail length. In addition, activity yield was improved with the implementation of an intermediate partial elution recycle procedure.
