SpADS and SNAP-NAPPA Microarrays towards Biomarkers Identification in Humans: Background Subtraction in Mass Spectrometry with E.coli Cell Free Expression System

Abstract

Claudio Nicolini, Rosanna Spera and Eugenia Pechkova

We present a useful approach towards for biomarkers identification in an innovative self-assembling protein microarray based on “Nucleic Acid Programmable Protein Array” (NAPPA) and SNAP tag coupled to E.coli cell free expression system. This approach prove capable to resolve the “background” problem associated to the above label free detection system for the identification of proteins and of protein-protein interaction in humans that could become used in clinical practice.
