Tapia & Volkmer (2009) "Exploring and profiling protein function with peptide arrays" in: Methods in molecular biology (eds. Chiari). Humana Press
This work reviews the peptide array technology focusing on technological advancements, oriented immobilization of peptide probes, and some interesting applications. Going along the philosophy of the monography series, we give some general recomendations on methods and instruments.

This work was carried out to adapt "building block" approaches for the generation of phosphopeptides through resine-supported solid-phase peptide synthesis to the spot-technology, which relies on cellulose as support. It compares different coupling strategies for the incorporation of protected phoshoaminiacids into determined positions of synthetic peptides. We find that the use of EEDQ (caution!, neurotoxic) as coupling activator is the most efficient strategy in our comparison.

This work analyses the predictive potential of microarray-based binding assays. Fluorescent SI-measurements were used to fit a mass-action derived model estimating the observed affinity (equil. diss. const.).

This work analyses the quantitative potential of measurements derived from peptide macroarray-based immunobinding assays. Chemoluminiscent signal intensity data was confronted with independent "golden stardard" measurements (surface plasmon resonance-based binding assays on a BIAcoreX maschine).
