On the Binding of Congo Red to Amyloid Fibrils [PDF]
Angewandte Chemie - International Edition, 2020 AbstractAmyloids are characterized by their capacity to bind Congo red (CR), one of the most used amyloid‐specific dyes. The structural features of CR binding were unknown for years, mainly because of the lack of amyloid structures solved at high resolution. In the last few years, solid‐state NMR spectroscopy enabled the determination of the structural
