In response to the rapidly growing field of proteomics, the use of recombinant proteins has increased greatly in recent years. Recombinant hybrids containing a polypeptide fusion partner, termed affinity tag, to facilitate the purification of the target polypeptides are widely used. Many different proteins, domains, or peptides can be fused with the target protein. The advantages of using fusion proteins to facilitate purification and detection of recombinant proteins are well-recognized. Nevertheless, it is difficult to choose the right purification system for a specific protein of interest. This review gives an overview of the most frequently used and interesting systems: Arg-tag, calmodulin-binding peptide, cell ulose-binding domain, DsbA, c-mye-tag, glutathione S-transferase, FLAG-tag, HAT-tag, His-tag, maltose-binding protein, NusA, S-tag, SBP-tag, Strep-tag, and thioredoxin.
