Figure 4.
Oligomer size distribution of Aβ analogues. (A) 60 μM of each peptide was cross-linked using PICUP, fractionated by SDS-PAGE and silver-stained. Positions of molecular weight standards are shown on the left. The gels are representative of three independent experiments. (B) Densitometric analysis of the oligomer size distributions. The data show mean ± SEM of three independent experiments.
