[0002] Protein separation and purification is widely used in biochemical research applications and is an important operating technique. A typical eukaryotic cell can contain thousands of different proteins, some of which are very abundant and some of which contain only a few copies. In order to study a certain protein, it must first be purified from other proteins and non-protein molecules. Protein purification takes advantage of the inherent similarities and differences between different proteins, using the similarities between various proteins to remove the contamination of non-protein substances, and using the differences between each protein to purify the target protein from other proteins. Each protein has differences in size, shape, charge, hydrophobicity, solubility and biological activity. These differences can be used to extract proteins from mixtures such as E. coli lysates to obtain recombinant proteins.
