Effects of Ni(II) ions on formation of SDS-stabilized Aβ₄₂ oligomers (AβO_0.05%SDS and AβO_0.2%SDS) studied by BN-PAGE. Lane 1: Monomers; Lanes 2–5: AβO_0.05%SDS oligomers with respectively 0, 10, 100, and 500 µM Ni(II) ions; Lanes 6–9: AβO_0.2%SDS oligomers with respectively 0, 10, 100, and 500 µM Ni(II) ions.
