Cell-based protein purification systems

Cell-based protein purification systems offer advantages over conventional protein purification approaches which rely mostly on chromatographic methods to stepwise enrich for a desired protein of interest. We are developing approaches by which cells are engineered to produce their own affinity matrix to selectively sequester a desired recombinant protein. This allows for the expression and affinity purification of desired proteins in a single host, thereby obviating the need for external chromatographic purification.
