Popis: Additional file 4. Morphological analsysis of ��Syn_RT-QuIC reaction products generated by MSA-P and MSA-C samples at ITA-lab. ��Syn_RT-QuIC reaction products were properly diluted and 10 ��L of the final dilutions was dropped onto 200-mesh Formvar-carbon coated nickel grids for 30 min and the remaining drop was blotted dry using filter papers. Samples were stained with 25% Uranyl Acetate Replacement (UAR, negative staining) for 10 min, the solution was removed using filter papers and the grids were air-dried for 15 min before the analyses. Images were recorded at 120 kV with a FEI Tecnai Spirit, equipped with an Olimpus Megaview G2 camera. Rec-��Syn amyloid fibrils were detected in all ��Syn_RT-QuIC products seeded with MSA-P samples, except for MSA-P_10 and MSA-P_11. In constrast, none of the MSA-C samples induced the formation of rec-��Syn fibrils (except for occasional, rare and short aggregates detected in MSA-C_1, MSA-C_3 and MSA-C_6). All TEM images were taken at the same magnification (scale bar: 200 nm).
