Abstract
Peptide microarrays can be used to measure the activity of multiple protein kinases (PKs), which can be used to elucidate kinomics for drug discovery and diagnosis. Here we demonstrated a new microarray for ratiometric detection of the activity of PKs using peptide nucleic acid (PNA)-tagged peptides labeled with two different fluorophores, Cy3 and Cy5. We successfully detected cellular PK activities based on ratiometry, and applied the system for evaluation of an inhibitory drug.
