Developing site-specific immobilization strategies of peptides in a microarray.
In peptide-based microarrays, most existing methods do not allow for site-specific immobilization of peptides on the glass surface. We have developed two new approaches for site-specific immobilization of kinase substrates onto glass slides: (1) slides were functionalized with avidin for attachment of biotinylated peptides; and (2) slides were functionalized with thioester for attachment of N-terminally cysteine-containing peptides via a native chemical ligation reaction.
