Analysis of 5000 year-old human teeth using optimized large-scale and targeted proteomics approaches for detection of sex-specific peptides

The study demonstrates the high potential of MS-based proteomics coupled to an iterative database search strategy for the in-depth investigation of ancient proteomes. An efficient targeted PRM MS-based approach, although limited to the detection of a single pair of sex-specific amelogenin peptides, allowed confirming the sex of individuals in ancient dental remains, an essential information for paleoanthropologists facing the issue of sex determination and dimorphism.
