Fig. 4From: Dynamic changes of oligomeric amyloid β levels in plasma induced by spiked synthetic Aβ42 Effect of amyloid-β 1–42 peptide (Aβ42) spiking and incubation in large scale (Alzheimer’s disease [AD] and healthy normal control subjects). Each sample was incubated for 144 h after being spiked with 10 ng/ml Aβ42. To measure amyloid-β oligomers, a multimer detection system assay was used. ***p < 0.001 versus healthy normal control values. RLU Relative luminescence unitsBack to article page
