Proteins interacting with diverse ligands - proteins, peptides or DNA - are the basic principles underlying many biological processes, such as antigen-antibody binding, signal transduction or receptor binding.
The technique of oligopeptide synthesis on a cellulose membrane and the subsequent binding assays allow the investigation of protein interactions. A particular advantage of these peptide arrays (SPOT - technology) is the high number of oligopeptide probes that can be tested in parallel. Detailed protocols for peptide synthesis, and the analysis of protein-protein, protein-DNA interactions as well as epitope mapping are presented in this manual. It is ideally suited not only for basic research laboratories but also for diagnostic and therapeutic applications since many diseases are related to dysfunctions in protein recognition and binding.

Detailed step-by-step protocols, including troubleshooting sections and many hints and comments from the authors The technology described is ideally suited to cope with the flood of data derived from the Human Genome Project The protocols are well established and are provided by authors with plenty of experience with this technology
