Fig. 2: Relationship between plasma sample dilution and normalized intensity.

A The relationship between plasma sample dilution and normalized intensity of the PAβ V1.0 and PAβ V2.0 assays. Three technical replicates were performed for each volume. Data were presented as mean values +/− standard deviation. Both Aβ1-40 and Aβ1-42 were normalized using the Aβ1-38 IS. B The S/N ratios of measurements using plasma samples with various volumes (50 μl–250 μl) were compared in three technical replicates between the PAβ V1.0 and the PAβ V2.0 assays for Aβ1-40 and Aβ1-42. Data were presented as mean values +/− standard deviation.
