abstract = {Still, there is need for significant improvements in
reliable and accurate diagnosis for Alzheimer's disease (AD)
at early stages. It is widely accepted that changes in the
concentration and conformation of amyloid-β (Aβ) appear
several years before the onset of first symptoms of
cognitive impairment in AD patients. Because Aβ oligomers
are possibly the major toxic species in AD, they are a
promising biomarker candidate for the early diagnosis of the
disease. To date, a variety of oligomer-specific assays have
been developed, many of them ELISAs. Here, we demonstrate
the sFIDA assay, a technology highly specific for Aβ
oligomers developed toward single particle sensitivity. By
spiking stabilized Aβ oligomers to buffer and to body
fluids from control donors, we show that the sFIDA readout
correlates with the applied concentration of stabilized
oligomers diluted in buffer, cerebrospinal fluid (CSF), and
blood plasma over several orders of magnitude. The lower
limit of detection was calculated to be 22 fM of stabilized
oligomers diluted in PBS, 18 fM in CSF, and 14 fM in blood
plasma.},
