Proteomics study of 1630 death registries

The death registries of the plague epidemics of 1630, stored at the Archivio di Stato of Milano, have been interrogated via the EVA film technology (ethyl vinyl acetate film studded with crushed strong anion and cation exchangers as well as C8 resins). The EVA diskettes have been left in contact with the lower right margins of 10 different foils pertaining to the peak months of the raging disease (June through end of September) for 60-90 min and then the captured material, after elution and digestion, analyzed by mass spectrometry.
