Abstract

While soluble amyloid-β (Aβ) oligomeric assemblies are known to be involved in the complex Alzheimer's disease (AD) pathology, their detailed composition and neurotoxicity are still not elucidated. Identification of AD-related Aß species in brain tissue or accessible body fluids would thus provide valuable insight in AD progression. Here, Aß variants from AD patient blood serum are studied using Microfluidics and MALDI Mass Spectrometry (MIMAS). Sample preparation and MALDI analysis are performed in situ to minimize sample loss and improve sensitivity. The MIMAS assay, performed entirely on a microfluidic platform, reveals significantly different signatures between native and serum Aß peptides.
