Peptide arrays differ from conventional peptide synthesis in that hundreds upon thousands of peptides are synthesized and presented on a planar surface at a time. While direct synthesis of peptide arrays on a functionalized surface is feasible, reprinting of pre-made peptides offers flexibility and reproducibility and drastically reduces cost when multiple copies of the same or related peptide arrays are needed. CelluSpot, a method developed by Intavis, opens a new route in peptide array synthesis and printing and overcomes certain limitations of the SPOT membrane. This technique was used to produce hundreds of phosphotyrosine-oriented peptide array libraries for determining the specificity of the Src homology 2 (SH2) domain.
