Kinetic curves of TauK18 and TauK19 seeding activity in the ankle (A, K) and cervical (F, P) sites, respectively. Each dot represents the mean (±SE) of ThT fluorescence intensity of all samples tested per group against time. The dotted line indicates the selected threshold at 10.000 arbitrary units (AU). B, G, L, Q Scatter plot of final ThT fluorescence intensities: dots represent the mean values of the final ThT fluorescence intensity for individual patients and bars the mean of the group. C, H, M, R Box and Whisker Plot showing the Lag time defined as the reaction time required to pass the threshold of 10.000 AU. The dotted line shows the selected time points (7 h for TauK18 or 18 h for TauK19) to define the positive and negative subjects. D, I, N, S Box and Whisker Plot showing the T50 defined as the reaction time required to reach 50% of the maximum fluorescence detected. E, J, O, T Seeding score defined as the number of replicates out of three that cross the threshold of 10.000 AU at 7 h. Each dot represents a patient and bars the mean of the group.
