Chemical array technology is a powerful tool for high-throughput screening of small-molecule ligand- protein interactions. A chemical array is a collection of small-molecule compounds spotted and immobilized on a glass slide surface, providing a multiplex platform to identify small-molecule compounds binding to a protein of interest in high-throughput screening. Several research groups have developed a variety of methods for the immobilization of small molecules onto a solid matrix. We have developed a unique photo-cross-linked chemical array for immobilizing small molecules in a functional-group-independent manner. In this chapter, we describe in detail a protocol for the construction of a photo-cross-linked chemical array and its application for ligand screening by using a tag-fused protein.
