Abstract Aptamers are oligonucleotide molecules able to recognize very specifically proteins. Among the possible applications, aptamers have been used for affinity
chromatography with effective results and advantages over most advanced protein
separation technologies. This chapter first discusses the context of the affinity
chromatography with aptamer ligands. With the adaptation of SELEX, the chemical
modifications of aptamers to comply with the covalent coupling and the separation
process are then extensively presented. A focus is then made about the most
