Figure 1

Spontaneous generation of human misfolded recombinant proteins. Graphical representation of the emergence of spontaneous protein misfolding evaluated through Western blot analysis in SDS-PAGE for each round of recPMCA (outlined as R01–R30). Different human recombinant proteins were grouped according to the substitution and the polymorphism at codon 129 and according to the disease [genetic Creutzfeldt-Jakob disease (gCJD), Gerstmann-Sträussler-Scheinker syndrome (GSS) and Fatal Familial Insomnia (FFI)] with which they are associated. Every experiment contained 4–5 tubes (intra-experimental replicates) and was performed in duplicate as shown. The percentage of positive tubes (tubes showing a protease resistant signal after digestion with 80 μg/ml of PK) after each round of recPMCA was noted with different intensities of grey, as shown in the legend below the figure. WT: wild type human rec-PrPs.
