Evaluation of the effect of various main elements on the PrPSc detection by real-time quaking-induced conversion assay.

ABSTRACT: In order to definitively diagnosis sporadic Creutzfeldt‑Jakob disease (sCJD), brain tissue is currently required. Therefore, there is a great need for tests that can detect sCJD in body fluids or other types of tissues. Different variables, including the amount of recombinant celluar prion protein (rPrPC), salt, cleaning surfactants and thioflavin T (ThT), in human cerebrospinal fluid (CSF) were evaluated. The reagent concentrations of 1X PBS, 170 mM NaCl, 1 mM EDTA, 0.01 mM ThT and 0.001% SDS, and the amounts of 10 µg rPrPC and 10 µl CSF were considered to be optimal for the real‑time quaking‑induced conversion (RT‑QuIC) assay. Using these conditions, the RT‑QuIC assay for prion protein (PrPSc) detection was observed to be sensitive to 10‑8 diluted brain homogenates of hamsters infected w
