A conscious rethink
Brain tissue is ubiquitous in the archaeological record. Multiple, independent studies report the finding of black, resinous or shiny brain tissue, and Petrone et al. [2020 “Heat-induced Brain Vitrification from the Vesuvius Eruption in C.E. 79.” N Engl J Med. 382: 383–384; doi:10.1056/NEJMc1909867] raise the intriguing prospect of a role for vitrification in the preservation of ancient biomolecules. However, Petrone et al. (2020) have not made t…
DeamiDate 1.0
Contamination is a potential problem in the study of ancient proteins, either from prior handling of the sample, laboratory consumables, or cross-sample carryover from mass spectrometers. Recently, deamidation of glutamine has been proposed as a measure for assessing the degradation of ancient proteins. Here, we present deamiDATE 1.0, a method for the authentication of ancient proteins using measure of site-specific deamidation rates. We test thi…
New insights into Neolithic milk consumption through proteomic analysis of dental calculus
There has long been debate over the origins of dairy consumption within European populations. Whilst it was previously assumed that lactase persistence (LP) was under positive selection following the advent of agriculture, recent genetic studies of prehistoric human remains have revealed LP may have only emerged in Europe in the last 4000 years. These findings stand in contrast to organic residue analysis of Neolithic pottery indicating the utili…
Preservation of the metaproteome
Proteomic analysis of dental calculus is emerging as a powerful tool for disease and dietary characterisation of archaeological populations. To better understand the variability in protein results from dental calculus, we analysed 21 samples from three Roman-period populations to compare: 1) the quantity of extracted protein; 2) the number of mass spectral queries; and 3) the number of peptide spectral matches and protein identifications. We foun…
