Regarding the oligomer distribution, dimers show the highest concentration, with an overall trend of lower concentration the bigger the oligomeric species, although the trend is not perfectly monotonic indicating a higher instability of some oligomeric sizes, as previously reported for Aβ40. 47 This is the case regardless of the lighting time applied to the reaction ( Figure 3 ), or at which time point in the aggregation process the sample is collected ( Figure 7 C,D).
