Protein-protein interactions mediate most processes in the living cell. Impaired protein interactions can lead to disease, which is why protein interactions are valuable drug targets. Therefore, it is extremely important to understand these interactions at the molecular level. Protein interactions are studied using a variety of techniques. Peptides are used to study and are powerful tools for protein interaction.

Synthetic peptide arrays were developed in the 1990s and are an exciting and rapidly growing technology with a wide range of possibilities for applications in basic and applied life sciences.

Peptide libraries are versatile and have proven important for determining the substrate specificities of enzymes, profiling antibodies, mapping epitopes, studying ligand-receptor interactions, and identifying ligands that mediate cell adhesion. The arrays typically comprise hundreds to thousands of distinct peptide sequences. The technique has become a powerful tool for high-throughput approaches in biology and biochemistry.

Nevertheless, peptide arrays are not yet a standard method in the laboratory and in the drug development process, especially compared to oligonucleotide arrays, and the potential of peptide libraries has not yet been fully recognized and exploited.
