SDS-PAGE Western blot analysis of the AB5-3 and pan-Aβ 4G8 antibodies. Freshly dissolved synthetic Aβ variants (2 μg each) were probed to a membrane. (A) The polyclonal AB5-3 antibody detects Aβ5–42 trimers and tetramers while (B) the monoclonal pan-Aβ antibody 4G8 detects different sizes of all Aβ species.
