In this work, the “bottom-up” protein identification process is described, from sample digestion to the final database search result. Both MALDI and LC-MS approaches to the identification issue are illustrated. The state-of-the-art of these technique is outlined along with several recent applications, such as MSn data acquisition and chemical derivatization of peptides.
