Fast (120 s) and high-throughput (more than six samples at once) in-gel trypsin digestion of proteins using sonoreactor technology has been achieved. Successful protein identification was done by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, MALDI-TOF-MS. Specific identification of the adenylyl-sulphate reductase alfa subunit from a complex protein mixture from Desulfovibrio desulfuricans ATCC 27774 was done as a proof of the methodology. The new sample treatment is of easy implementation, saves time and money, and can be adapted to online procedures and robotic platforms.
