Affinity tags



In 1983, the first gene fusion approach for affinity purification of recombinant proteins was described ((1). Fusions to the staphylocoocal protein A (see figure) made it possible to perform one-step purification using IgG-Sepharose (1, 2 and 3). In 1988, a large number of alternative systems were subsequently described (Table 1) all based on the same principle of a one-step purification using a specific affinity tag. The first report on a dual affinity fusion approach was published in 1989 (5). The use of affinity tags for purification of recombinant proteins has since become wide-spread as a versatile tool in bioscience for the affinity capture of recombinant proteins.
