Fig. 1.

Representative dose-response curves using the amyloid-β 1–42 peptides (Aβ_1–42) from Quanterix and Fujirebio. For each calibration curve, average enzymes per bead (AEB) (n = 3) and coefficient of variation (CV) of each calibration level are shown in the embedded table. The signals from the Quanterix Aβ_1–42 peptide were approximately threefold higher than those from the Fujirebio Aβ_1–42 peptide
