Protein purification is a common task in biotechnology this process involves producing the cells or organisms that make the protein and separating the protein away from everything else in the cell. Protein purification is a series of processes intended to isolate one or a few proteins from a complex mixture, usually cells, tissues or whole organisms protein purification is vital for the characterization of the function, structure and interactions of the protein of interest. Protein engineering techniques are an essential part of customizing or producing proteins with specific properties which can be applied in various industrial processes. To simplify the purification of recombinant proteins by affinity chromatography, a tag of protein/peptide or other molecule with known size is usually incorporated into the proteins.
Rebecca wissner of the university of pennsylvania describes the expression of green fluorescent protein (gfp) in e coli and the purification of the protein. To achieve this several protein purification methods are typically used, in a series of purification steps each protein purification step usually results in some degree of product loss therefore, an ideal protein purification strategy is one in which the highest level of purification is reached in the fewest steps.
