This study aims to investigate detergent sodium deoxycholate (SDC) and sodium dodecyl sulphate (SDS) treatments, with a focus on each detergent's ability to enhance the extraction of immune-related proteins from camel milk fat globular membrane. Milk was separated into cream and skimmed milk. The cream was then treated using 0.4 % SDS, 2 % SDC, 6 % SDC or 10 % SDC. Extracted proteins were trypsin digested and analysed using liquid chromatography-tandem mass spectrometry. Higher SDC concentrations (6 % and 10 %) resulted in marginal improvements in protein identification (44 unique protein groups). Protein abundance distributions showed minimal differences across …

Prion diseases are fatal neurodegenerative disorders caused by the misfolding of the normal prion protein (PrPC) into its infectious form (PrPSc). While the zoonotic potential of chronic wasting disease (CWD) remains uncertain, the presence of prions in food products raises public health concerns. Additionally, therapeutic strategies for prion diseases remain limited. This thesis presents a methodological exploration of the Protein Misfolding Cyclic Amplification (PMCA) technique to address these challenges in two key areas: (1) detecting CWD prions in processed meats subjected to common cooking procedures, and (2) identifying potential anti-prion compounds through a high-throughput PMCA adaptation. …
