["Paleoproteomic study of the Iceman's brain tissue.", 'We report the first use of shotgun proteomics to detect the protein expression profile of buccal swabs and cloth samples from two 500-year-old Andean mummies.', 'Identification of ancient biological samples from the 1991-discovered and more than 5300-year-old Tyrolean mummy, also called iceman or Oetzi, is very difficult. T', 'To determine whether a 2,700-year-old tumor can be reliably diagnosed using microscopic and proteomic techniques ']
