Selectivity of the Amyblood and Quanterix amyloid assays. (A) The highest %recovery measured with the Amyblood Abeta1-42 assay was 125% in the presence of 6 pg/mL Abeta1-42 and 15 pg/mL Abeta1-40. (B) The highest %recovery measured with the Quanterix Abetax-42 assay was 1021% in the presence of 1 pg/mL Abeta1-42 and 130 pg/mL Abeta1-40. (C) The highest %recovery measured with the Amyblood Abeta1-40 assay was 110% in the presence of 3 pg/mL Abeta1-40 and 6 pg/mL Abeta1-42. (D) The highest %recovery measured with the Quanterix Abetax-40 assay was 115% in the presence of 130 pg/mL Abeta1-40 and 15 pg/mL Abeta1-40. The concentrations in buffer nearest to physiological Abeta1-42 and Abeta1-40 combinations in plasma as measured with this assay are indicated with an asterisk.
