Data from: Validation of a Real-Time Quaking-Induced Conversion (RT-QuIC) Assay Protocol to Detect Chronic Wasting Disease using Rectal Mucosa of Naturally Infected, Pre-Clinical White-Tailed Deer (<i>Odocoileus Virginianus</i>)

<h2>Purpose of the study:</h2><p dir="ltr">The diagnostic performance of a standardized RT-QuIC protocol using two sources of assay substrate was studied for detecting chronic wasting disease (CWD) in mock rectal mucosa biopsy samples from farmed white-tailed deer (<i>Odocoileus virginianus</i>).</p><h2>The repository files</h2><h3>RTQuIC_reactions.xlsx</h3><p dir="ltr">The entire collection of reaction data used to determine the diagnostic performance of a standardized RT-QuIC protocol (DOI: <a href="https://www.protocols.io/private/F0DCD5C6907C11EC84BC0A58A9FEAC02" rel="noreferrer" target="_blank">dx.doi.org/10.17504/protocols.io.yxmvmn2y6g3p/v1</a>). The variables (columns) in the dataset include the name of the substrate source, the plate reader ID, plate well position, assay time in fractional hours, the ThT signal measured in relative fluorescence units, and also the following animal information for the sample tested: an anonymized white-tailed deer ID, sex, age in years, <i>PRNP</i> genotype at codons 95 and 96, and stage of infection. The animal's stage of infection was determined by immunohistochemistry for CWD-associated prion protein accumulation in the medial retropharyngeal lymph nodes (MRPLN) and the obex. All deer were from farms on which infected deer had been previously detected; thus all deer were considered exposed. Based on the results of CWD-IHC, deer were classified for CWD as infection not detected in these tissues (ND), as early preclinical when CWD-IHC positive in only the MRPLN, and as late preclinical when CWD-IHC positive in both of MRPLN and obex. No deer were reported to be clinical at the time of sample collection.</p><h3>Supp Figure 1-###.png</h3><p dir="ltr">A series of 26 PNG files representing the reaction data from RTQuIC_reactions.xlsx.</p><p dir="ltr">Each PNG file plots the ThT data acquired from a 96-well plate over time. Each file includes a header that identifies the substrate source and plate ID (1-13 for each substrate source). Each plot indicates the white-tailed deer ID being tested and shows the quadruplicate reactions recorded. Also included are the quadruplicate reaction data for the plate negative control (a sample from an ND deer) and positive control (a late preclinical deer).</p>
