淀粉样原纤维的形成与许多神经退行性疾病有关。为了阐明纤维形成的机制,广泛使用硫磺素T(ThT)荧光测定。ThT是一种荧光染料,其选择性地结合淀粉样蛋白原纤维并表现出荧光增强,这使得能够定量分析原纤维形成过程。然而,详细的约束机制仍不清楚。在这里,我们获得超氧化物歧化酶1(SOD1)的原纤维形成的实时配置文件,使用高灵敏度的流变NMR光谱和检测弱和强之间的相互作用ThT和SOD1原纤维在一个时间依赖性的方式。ThT与纤维相互作用的实时信息将有助于理解ThT与纤维的结合机制。此外,我们的方法提供了一种替代方法来分析原纤维的形成。
Amyloid fibril formation is associated with numerous neurodegenerative diseases. To elucidate the mechanism of fibril formation, the thioflavin T (ThT) fluorescence assay is widely used. ThT is a fluorescent dye that selectively binds to amyloid fibrils and exhibits fluorescence enhancement, which enables quantitative analysis of the fibril formation process. However, the detailed binding mechanism has remained unclear. Here we acquire real-time profiles of fibril formation of superoxide dismutase 1 (SOD1) using high-sensitivity Rheo-NMR spectroscopy and detect weak and strong interactions between ThT and SOD1 fibrils in a time-dependent manner. Real-time information on the interaction between ThT and fibrils will contribute to the understanding of the binding mechanism of ThT to fibrils. In addition, our method provides an alternative way to analyze fibril formation.
