Used extensively in biological research for detecting and quantifying amyloid fibrils, particularly in Alzheimer's disease studies. Binds specifically to the beta-sheet structures of amyloid aggregates and exhibits enhanced fluorescence upon binding, making it ideal for fluorescence microscopy and spectroscopy. Commonly used in histology to stain tissue sections for the presence of amyloid plaques. Also applied in high-throughput screening assays to identify compounds that inhibit or promote amyloid formation. Useful in monitoring protein aggregation in real time during in vitro experiments.
