Novel Aggregation-Specific Fluorogen Monitors Prefibrillar Protein Aggregation by Fluorescence Polarization

Highly ordered protein aggregates, termed amyloid fibrils, are associated with a broad range of diseases, many of which are neurodegenerative for example Alzheimer’s and Parkinson’s. The transition from soluble, functional protein to insoluble amyloid fibril occurs via a complex process involving the initial generation of highly dynamic early stage aggregates or prefibrillar species. Prefibrillar species are proposed to play a key role in the cytotoxicity of amyloid fibrils. Therefore, novel probes that have broad applicability in the detection of prefibrillar species of amyloidogenic proteins are actively being sought.
