Quantification of RML and ME7 PrP27-30 in brain at various days post infection (dpi). (a) 1 mg of brain from scrapie-infected mice at was analyzed by immunoblotting after digestion with 100 μg/ml PK. PrPC is shown as a migration control. Signals were detected by 4H11 monoclonal antibody. Mr is shown on the right. (b) Comparing PrP27-30 concentrations measured by quantitative RT-QuIC and quantitative immunoblot. The brains of RML-inoculated mice 90 dpi to 170 dpi and ME7-inoculated mice 90 to 150 dpi were chosen regarding the capacity of immunobloting to detect PrP27-30 from the time-point not earlier than 90 dpi. The significance (p value) was calculated with two-way ANOVA by using detecting methods and time-points as the variables. Shown data are mean and s.e.m (n = 5).
