Peptide Microarrays Methods and Protocols
Due to their versatility, along with the diminishing costs of library synthesis and the growth of commercial support, peptide microarrays will likely expand beyond being just a research tool into an adaptable and powerful platform to be harnessed for wide

Preface The ability to directly interrogate protein interactions in a high-throughput format provides an unprecedented opportunity to dissect the complex molecular architectures of living systems. Traditional molecular biology techniques provide valuable information on the expression, structure, and function of proteins; nonetheless, these methods are unable to provide the massively parallel analysis capacity which is essential to map an entire proteome or to accomplish the present-day drug discovery programs. Parallel sensing using arrayed systems has proved to be successful in genomic research where DNA microarrays are widely used for large-scale analysis of gene expression. However, the protein equivalent of the DNA microarrays poses a more difficult challenge, especially in the identification of suitable high-affinity capture ligands, which retain their specificity and functionality following immobilization on the arrayed sensor substrate. Synthetic peptides have some very interesting features as capture ligands in microarray experiments: they are easy to synthesize and manipulate, highly stable, and inexpensive. More importantly, since peptide ligands can be modeled to act as a bindin
