The screening of compound arrays in in vitro bioassays has developed into a powerful tool for the identification of biologically active substances. In the past decade, this technology has increasingly been applied to immunology. As the specificity of the immune system is determined by antigen detection via receptors on B and T cells, targeting the specificity of these immune receptors with random arrays is unique in its ability to generate general and quantitative information on cellular (cross-)reactivity. Synthetic array studies have been useful for identification of epitopes and antigens from databases by defining recognition patterns, isolation of synthetic peptides capable of modulating T cell responsiveness, characterisation of TCR promiscuity, and identification of functionally cross-reacting peptides that are potentially involved in molecular mimicry.
