1. Dot-blot epitope mapping of Aβ1–42 conformers bound by TTR and IC50 values of binding.
Dot-blot epitope mapping of Aβ1–42 conformers bound by TTR and IC50 values of binding. A, TTR-bound Aβ1–42 conformers at the hydrophobic central region was demonstrated by epitope mapping dot blot. Aβ conformers (25 μm, 2 μl) were spotted on nitrocellulose membrane and incubated with antibody specific to different regions (N terminal Aβ3–10; middle, Aβ18–22, Aβ16–21; C terminal, Aβ30–35, Aβ35–39). The second spot on each strip is spotted with oligomers that were A11 (oligomer-specific) antibody positive, whereas the third spot is not. B, Quantification of binding (IC50) of biotinylated TTRs to Aβ1–42 conformers immobilized on Nunc Maxisorb plates.
