In drug development research, the elucidation and understanding of the interactions between physiologically active substances and proteins that numerous genes produce is important. Currently, most commercially available drugs and physiologically active substances have been brought to market without knowledge of factors interacting with the drugs and the substances. Affinity purification is a useful and powerful technique employed to understand factors that are targeted by drugs and physiologically active substances. However, use of conventional matrices for affinity chromatography often causes a decrease in efficiency of affinity purification and, as a result, more practical matrices for affinity purification have been developed for application in drug discovery research. In this paper, we describe the development of high-performance affinity beads (SG beads and FG beads) that enable one-step affinity purification of drug targets and the elucidation of the mechanism of the action of the drugs. We also describe a chemical screening system using our affinity beads. We hope that utilization of the affinity beads will contribute to the progress of research in chemical biology.
