A designed peptide chip: Protein fingerprinting technology with a dry peptide array and statistical data mining

Abstract

There has recently been increased interest in the potential for microarray technologies to study protein networks in a whole cell system within a single experiment. Protein-detecting microarrays are composed of numerous agents immobilized within a tiny area on solid surfaces to capture targeted proteins and to detect interactions in a high-throughput fashion. In this chapter, in order to extend the usability of peptide microarrays, we describe a novel dry peptide microarray format to obtain protein fingerprint (PFP) data sets and a statistical PFP data manipulation technique to quantitatively analyze targeted proteins. © 2009 Humana Press, a part of Springer Science+Business Media, LLC.
