|a We demonstrate that the microwave-assisted protein enzymatic digestion (MAPED) method can be successfully applied to the mass spectrometric characterization of proteins captured on the affinity surfaces of protein chips. The microwave-assisted on-chip tryptic digestion method was developed using a domestic microwave, completing the on-chip proteolysis reaction in minutes, whereas the previous on-chip digestion methods by incubation took hours of incubation time. For the model protein chips, antibody-presenting surfaces were prepared, where anti-α-tubulin1 and antibovine serum albumin (BSA) were immobilized on self-assembled monolayers. The resulting digestion efficiency, displaying sequence coverages of 30 and 14% for α-tubulin1 and BSA, respectively, was comparable to the previous time-consuming incubation studies. It allowed the characterization of immunosensed proteins by MASCOT search using peptide mass fingerprinting. In an example of this method for protein chip applications, BSA naturally involved in fetal bovine serum was unambiguously identified on a model protein chip by imaging mass spectrometry. This work shows that biomass spectrometry techniques can be implemented for surface mass spectrometry and biochip applications. Along with recent advances in imaging mass spectrometry, this technique will provide a new opportunity for high-speed, and thus high-throughput in the future, label-free mass spectrometric assays using protein arrays
