Affinity chromatography by His-Tag is one of the most widespread purification techniques for recombinant proteins. In many cases it requires an additional cleaning/polishing step. This application highlights the possibility of combining two subsequent chromatography protocols without manual interaction using the AZURA Bio LC system.
