Characterisation of South American camelid fibres by proteomics

ABSTRACT: The species-specific identification of fibre origin is essential in archaeology but reveals challenging for closely related species. This is particularly true between the four South American Camelids (SAC) species: alpaca, guanaco, llama and vicuña. The analysis of proteins extracted from hairs and/or yarns by proteomics has emerged as a powerful method to differentiate between species. However, for SAC, the database information available is very poor, which limits this approach. In this study, we analysed 42 modern and 4 archaeological reference samples from the four SAC species.

The proteomic analysis of hairs, yarns or textiles has emerged as a powerful method to determine species of origin, mainly used in archaeozoological research and fraud control. Differentiation between the South American camelid (SAC) species (the wild guanaco and vicuña and their respective domesticates the llama and alpaca) is particularly challenging due to poor database information and significant hybridization between species. In this study, we analysed 41 modern and 4 archaeological samples  ...[more]
