Figure Lengend Snippet: Fig. 1 PrPres western blot profiles in original E200K gCJD isolates and E200K gCJD-inoc- ulated human PrP-expressing mice. Western blot analysis of proteinase K-resistant prion protein (PrPres) profiles was performed on brain homogen- ates from both the original E200K gCJD patient isolates and transgenic mice expressing human PrP with Met129 (tgMet) or Val129 (tgVal) at codon 129. Mice were intracerebrally inoculated with 20 µL of 10% brain homogenate from E200K gCJD patients (n = 6 per group). Two serial passages were carried out in each mouse line (details in Table 1). The PrPres isoform (type 1 or type 2) was identified via SDS-PAGE and Western blot using the anti-PrP monoclonal antibody Sha31 (epitope YEDRYYRE). To control for PrPres isoform, MM1 sCJD (type 1) and VV2 sCJD (type 2) isolates were included in each gel. The PrPres isoform results for each passage and mouse line are summarized in Table 1

Article Snippet: Immunodetection was carried on PVDF membranes out using the monoclonal primary antibody Sha31 (1 μg/mL), which recognizes amino acids 145–152 (YEDRYYRE) of PrP, and an anti-mouse HRP-conjugated secondary antibody (Biorad) [16].

Figure Lengend Snippet: Fig. 3 PrPres western blot in the brains of tgMet mice inoculated with brain and peripheral tissues from E200K gCJD Patients. Western blot analysis of proteinase K-resistant prion protein (PrPres) was conducted on brain homogenates from transgenic mice expressing human PrP with Met129 (tgMet) after two serial intracerebral passages (n = 6 per group). The mice were inoculated with 20µL of a 10% homogenate prepared from brain or peripheral tissues of E200K gCJD patients (refer to Tables 1 and 2). PrPres was detected using the anti-PrP mon- oclonal antibody Sha31, targeting the YEDRYYRE epitope. For com- parison, MM1 sCJD (type 1) and VV2 sCJD (type 2) prion isolates were included as controls. PrPres isoform identification results for each passage are summarized in Table 2

Figure Lengend Snippet: Anti-PrP Sc activity of compounds 1 – 6 on prion-infected MovS6 cells. MovS6 cells were treated with the indicated ranges of concentrations of the molecules, and absolute ethanol was used as a negative control. After 6 days of culture, cell lysates were digested by proteinase K to reveal PrP Sc (top panels) or untreated to reveal PrP C (middle panels) or the loading control Tubulin (bottom panels). Proteins were separated in 10% Bis-Tris polyacrylamide gels and revealed using anti-PrP (Sha31) or anti-tubulin-specific antibodies. The blots shown are representative of two to three independent experiments that all produced similar results. Purealidin Q ( 1 ), aplysamine-2 ( 2 ) and aplysamine-1 ( 5 ) were able to reduce PrP Sc propagation, whereas pseudoceratinine A ( 3 ), aerophobin-2 ( 4 ), and pseudoceratinine-B ( 6 ) were not.

Figure Lengend Snippet: Relative pixel intensity analysis of PrP C expression in facial integumentary clarified 10% (w/v) gland homogenates of mule deer (A, C, E) and white-tailed deer (B, D, F). Background-adjusted average pixel intensities of PrP C bands of forehead (a-b), preorbital (c-d), and vestibular nasal glands were compared between lanes of SDS-PAGE PVDF membranes probed with anti-PrP Sha31. Unclarified white-tailed deer whole brain homogenate was used for reference. Sample size, mean, 95% confidence intervals, and significance by Mann-Whitney tests are shown.

Article Snippet: PrP C was probed with the mouse IgG 1 anti-prion protein SHA31 monoclonal primary antibody (1:10,000) (Cayman Chemical, USA) which binds to an epitope of 148–155 ( Odocoileus amino acid sequence).
