FIGURE 5.
Oligomer formation by Aβ42:Aβ40 ratios shows a monomer addition process and a dynamic distribution of oligomeric species. Mass spectra of the different ratios with the high molecular weight detection spectra as insets whereby the blue trace is t = 1 h, the black trace is t = 3 h, and the red trace is t = 6 h. a, pure Aβ40; b, 1:9 ratio; c, 3:7 ratio; d, pure Aβ42. These aggregation patterns for the different ratios are also presented in supplemental Table S1.
