The best way of protein purification is based on the properties of the proteins that are being exploited. It can be useful to know beforehand some physical properties of the protein, to facilitate the development of a suitable purification protocol. Ion exchange chromatography works as a common protein purification method that separates ions and polar molecules based on their affinity to the ion exchanger. Soluble molecules bind to oppositely charged insoluble stationary phase while passing through the column.

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. The purification process may separate the protein and non-protein parts of the mixture, and finally separate the desired protein from all other proteins.

Gerngross, David W. Wood. Protein science : a publication of the Protei. 005. This work combines two well-established technologies to generate a breakthrough in protein production and purification.

Recombinant proteins are produced for various applications in laboratory .

Among them, therapeutic applications have evolved into a mature field in recent years, affecting the face of contemporary medical treatment. 2. Comparison among the Production Systems of Recombinant Protein Therapeutics. Each purification methodology uses a particular feature of proteins.

Once purified, the product protein is self-cleaved from the granules and released into solution in a substantially purified form. This system has been successfully used at laboratory scale to purify several active test proteins at reasonable yield. By allowing the bacterial cells to effectively produce both the affinity resin and tagged target protein, the cost associated with the purification of recombinant proteins could be greatly reduced

In addition to chromatography, gas-solid distribution is also widely employed for purification . High resolution and fast separations are achieved since the small particles allow good efficiency with fast mobile phase velocities (one centimetre per second or higher).

In addition to chromatography, gas-solid distribution is also widely employed for purification, using special adsorbents called molecular sieves. These materials contain pores of approximately the same dimensions as small molecules. This technique is also important in purification, and separated substances can be automatically collected after the column using a fraction collector.

Two naturally produced in vivo affinity resin substitutes have been combined with a self-cleaving tag to develop two novel affinity-based purification technologies. The first resin alternative is polyhydroxybutyrate (PHB) granules and the second is elastin-like polypeptides (ELP). An engineered tripartite protein fusion is expressed in E. coli and purified through simple centrifugation. The intein self-cleaving tag then releases the target protein with a mild pH shift. The two systems have been successfully used at laboratory scale to purify more than a dozen proteins varying in size, complexity and activity, demonstrating the proof of principle, high purity and yield attainable. Hence, the cost associated with purification of recombinant proteins is reduced significantly to effectively that of just the culture medium. It is expected that this combination of improved economics and simplicity will constitute a significant breakthrough in both large-scale production of purified proteins and enzymes as well as high-throughput proteomics studies.
