abstract = {Early diagnostics at the preclinical stage of Alzheimer’s
disease is of utmost importance for drug development in
clinical trials and prognostic guidance. Since soluble Aβ
oligomers are considered to play a crucial role in the
disease pathogenesis, several methods aim to quantify Aβ
oligomers in body fluids such as cerebrospinal fluid (CSF)
and blood plasma. The highly specific and sensitive method
surface-based fluorescence intensity distribution analysis
(sFIDA) has successfully been established for oligomer
quantitation in CSF samples. In our study, we explored the
sFIDA method for quantitative measurements of synthetic Aβ
particles in blood plasma. For this purpose, EDTA, citrate
and heparin treated blood plasma samples from five
individual donors were spiked with Aβ coated silica
nanoparticles (Aβ-SiNaPs) and were applied to the sFIDA
assay. Based on the assay parameters linearity, coefficient
of variation and limit of detection, we found that EDTA
plasma yields the most suitable parameter values for
quantitation of Aβ oligomers in sFIDA assay with a limit of
detection of 16 fM.},
