Scientists working with recombinant proteins expressed in Escherichia coli probably use at least one liquid chromatography technique to purify their protein of interest. But liquid chromatography frequently requires a considerable amount of optimization, and usually involves several different chromatographic steps to rid the sample of contaminants.1 The ideal solution would be to create a resin that is completely specific to the target protein, enabling one-step purification. Affinity chromatogr
