Lagtime dependence on DPPC concentration. 6.8 μM Aβ(M1–40) was incubated with different concentrations of DPPC present as large unilamellar vesicles in 20 mM Tris/HCl, pH 7.4, 0.2 mM EDTA, 0.02% NaN₃ with 20 μM ThT. The half-time of completion, t_0.5, is defined as time at 50% of maximum intensity and the error bars represent the standard deviation from five wells.
