  1. AD, Alzheimer’s disease; ELISA, enzyme-linked immunosorbent assay; SAT, amyloid-beta oligomer values are higher than the highest loaded standard (50 pg/ml); ND, amyloid-beta oligomer values are too low to be detectable; TBS, Tris-buffered saline (20 mM Tris–HCl, pH 7.4, containing 150 mM NaCl).
