Short Aβ peptides slow down aggregation of Aβ₄₂ in vitro. Co-incubation of the shorter peptides Aβ₃₇ or Aβ₃₈ with Aβ₄₂ in a ratio of 1:10 reduces aggregation of Aβ₄₂ by more than threefold after 18 h under the assay conditions. Aβ₃₇ and Aβ₃₈ do not aggregate on their own. Data represent mean ± SEM of two experiments run in triplicate
