PAD-Beads enrichment enhances detection of PrPSc using real-time quaking-induced conversion.

ABSTRACT: OBJECTIVE:Scrapie is a transmissible spongiform encephalopathy (TSE) that naturally occurs in sheep and goats. This fatal neurodegenerative disease results from misfolding of the normal cellular prion protein (PrPC) to a pathogenic prion protein form (PrPSc). This pathogenic form, PrPSc, accumulates in the brain and lymphoid tissues. The presence of PrPSc can be detected by an in vitro conversion assay known as real-time quaking induced conversion (RT-QuIC). RT-QuIC has been used to detect PrPSc in a variety of biological tissues from brains to fluids. While this technique is both rapid and sensitive, enhancing the detection of prions would be valuable in the diagnostic laboratories. RESULTS:In this study, we assessed whether PrPSc detection sensitivity of RT-QuIC can be increased by enric
