93d38c6d-0323-4bf3-846e-ed52f62b4bbd Evon Hekkala Assistant Professor Biological Sciences Fordham University New York, NY, USA Previous Next All members MEMBER INFORMATION Evon Hekkala uses ancient and archival genomic methods to identify biological materials and to track their use and meaning at various points in history. Most recently, she is working with natural history collections to uplift Indigenous taxonomies and knowledge systems. Her current research is primarily focused on analyzing genomic data from archival and ancient biomaterials in combination with historical documentary resources to better understand species specific responses to anthropogenically and naturally induced environmental change. She works with communities to explore both formal and colloquial natural histories to decolonize our understanding of sources and meaning of the cultural heritage and natural history objects in museums.

1703895f-22de-4e6f-95b3-15ed3b534d95 Ashley Coutu Research Fellow Pitt Rivers Museum University of Oxford, UK Oxford, UK Previous Next All members MEMBER INFORMATION Ashley Coutu is currently a Research Fellow at the Pitt Rivers Museum, University of Oxford. Her background is as an archaeological scientist, and she primarily uses techniques and methods from biology and organic chemistry to understand archaeological materials. Her specialism is the use of stable isotope, ancient DNA, and proteomics analyses as applied to archaeological and museum collections of organic materials. She is particularly interested in method development in relation to the needs of museums for display and the care of objects in terms of their conservation. The geographical focus of her work is sub-Saharan Africa, and therefore most of her research is on the ivory trade, past and present, and the use of ivory as a raw material for crafting objects.

She investigates paints, coatings, adhesives, and the organic materials found in artworks across all ages using spectroscopy (FTIR), mass-spectrometric (GC/MS, Py-GC/MS. MALDI, LCMS) and immunological techniques (ELISA), with emphasis on natural and synthetic polymer identification and degradation. Her research interests include interactions between pigments and binders, especially proteins, polysaccharides, lipids, and their mixtures. ABM CONFERENCES ABM 2021 Poster Presenter Why Antibodies for Art Analysis? Materials from animal and plant sources (biological materials) have been used by artists to create all forms of artworks throughout time. The challenge to cultural heritage scientists is to provide meaningful and accurate information to curators, art historians, and conservators about the fats, lipids, gums, and proteins that are chemically changed by pigments and binder interactions. Antibodies offer one avenue for the investigation of proteins and polysaccharides. This presentation will describe the pros, cons, and future of this approach.

For the first time, hydrogen‑deuterium exchange mass spectrometry (HDX-MS) was implemented to explore the conformational alterations of proteins resulting from their interaction with inorganic pigments within the early stages of the paint film formation. Intact protein analysis and bottom-up electrospray-ionisation mass spectrometry strategies combined with progressively increasing deuterium incubation times were used to compare the protein structures of the model protein hen egg-white lysozyme (HEWL) extracted from newly dried non-pigmented films and newly dried films made from a freshly made mixture of HEWL with lead white pigment (2PbCO3 Pb(OH)2). The action of other pigments was also investigated, expanding the HDX study with a global approach to paint models of HEWL mixed with zinc white (ZnO), cinnabar (HgS) and red lead (Pb3O4) pigments. The results show structural modifications of HEWL induced by the interaction with the pigment metal ions during the paint formulation after drying and prior to ageing. Both the charge distribution of HEWL proteoforms, its oxidation rate and its deuterium absorption rate, were influenced by the pigment type, providing the first insights into the correlation of pigment type/metal cation to specific chemistries related to protein stability. Explore Julie Arslanoglu Cutting Through the Fat: Animal Species and Food Processing Techniques of Residues Found in Nineteenth-Century Edgefield Pottery As part of the exhibition, Hear Me Now: The Black Potters of Old Edgefield, South Carolina, The Met’s Department of Scientific Research (DSR) investigated organic food residues found inside large nineteenth-century alkaline-glazed stoneware vessels from the Old Edgefield District, South Carolina. “Examining Storage Jars from the American South” describes the driving questions about the jars’ use and the users’ lifestyle. Investigations reported in “The Inside (and Outside) Scoop: Scientific Analysis of Food Residues Inside the Jars from Old Edgefield, South Carolina” established that the heterogeneous residues are mostly oily materials with solid materials of various unknown origins. We hoped to gain more information about the jars’ contents from these residues, but to do so we need the sophisticated tools and expertise of our collaborators through ARCHE. Explore

This approach,however, is not always applicable due to the deterioration of the archaeological objects.Paleoproteomics was used as an alternative approach to identify the species of origin of fifteensamples of various tissues from approximately 600‑year‑old garments found in Nuulliit, northernGreenland. Proteomics revealed that a limited group of marine and terrestrial mammals were usedfor clothing production. The results obtained from the analysis of multiple types of clothing andelements, such as sinew thread and gut skin, suggest that their applications were based on theirproperties. When conclusive assignment of a sample to a species via proteomics was not possible, theobservation by transmitted light microscopy of feather and hair micromorphology, if not affected bydiagenesis, was used to improve the identification. The proteomic characterization of animal materialsused for clothing production in the Nuulliit archaeological context provides an insight into thepractical knowledge and the strategies adopted by the local Indigenous community to exploit naturalresources Explore
