Bioprocessing Part 3: Purification

This video is the third in a series of three videos depicting the major stages of industrial-scale fermentation: fermentation, separation/recovery, and purification. This program describes the process by which a biological product—in this case, a pure, concentrated solution of Green Fluorescent Protein (GFP)—is derived from clarified lysate. This is accomplished through multiple variations of two basic procedures: chromatography and filtration.
