Kolejny publiczny wykład (w języku angielskim) organizowany przez europejski projekt IPERION HS tym razem poświęcony będzie wykorzystaniu proteomiki (nauki o białkach) w badanaich dziedzictwa kulturowego.
Wykład zaprezentowany zostanie on-line przez dr Caroline Solazzo (badaczkę białek z Museum Conservation Institute, Smithsonian Institution) 16 marca 2023 o godz. 15:00 (naszego czasu). Podczas wykładu zostaną zaprezentowane współczesne techniki proteomiczne i spektroskopii masowej w badaniach białek włóknistych, w szczególności występujących w zabytkowych tkaninach i ubiorach.
Abstract
Proteomics is a growing discipline in cultural heritage studies. It has found many applications for the identification of proteinaceous media, such as binders and is becoming an important analytical tool in the study of animal-based documents and textiles. Fibrous proteins are highly-organized structural proteins forming filaments or sheets, providing strength and resistance. They include collagens, keratins and fibroins found in skin, hair and silk that make up many types of cultural objects. Species identification is often the main reason to use proteomics on animal fibre or skin, especially for difficult archaeological samples where the visual examination is not conclusive. But, while fibrous proteins are ubiquitous in cultural heritage, they are also highly perishable. Proteomics offers new tools for curators and conservators to better understand the composition and degradation of these artefacts. Access to instrumentation, the development of protocols adapted to ancient proteins and the creation of targeted databases are common challenges in the field of cultural heritage proteomics. This lecture will review current proteomics and mass spectrometric techniques used for the study of fibrous proteins, in particular, as used in historical textiles and garments.
