Table 2. Delay of Aβ-induced paralysis in C. elegans strain CL4176.

PT₅₀ are median values describing the point in time, when exactly 50% of the worms are paralysed. Experiments were conducted in different test series with slightly differing values of the control; p values compared to the respective control.
