In downstream processing, large-scale chromatography plays an important role. For its development, screening experiments followed by pilot-plant chromatography are mandatory steps. Here we describe fast, simple, and inexpensive methods for establishing a preparative chromatography for the separation of complex protein mixtures, based on sample displacement batch chromatography. The methods are demonstrated by anion-exchange chromatography of a human plasma protein fraction (Cohn IV-4), including the screening step and upscaling of the chromatography by a factor of one hundred. The results of the screening experiments and the preparative chromatography are monitored by SDS-PAGE electrophoresis. In summary, we provide a protocol, which should be easily adaptable for the chromatographic large-scale purification of other proteins, in the laboratory as well as in the manufacturing of biopharmaceuticals. These protocols cover the initial piloting steps for establishing a large-scale sample batch chromatography. The results from the piloting steps may also be applied for packed columns for performing simulated-moving-bed (SMB) chromatography rather than batch chromatography.
