This manuscript describes the chemical synthesis of a compound similar to fluorene and Congo red, including characterization of its spectral properties. It was shown that the dye, during interaction with amyloid-like fibrils of several proteins (lysozyme, insulin, and beta-2-microglobulin), has the ability to change fluorescent spectrum. In contrast, monomeric forms of these proteins did not induce
该手稿描述了类似于芴和刚果红的化合物的化学合成,包括其光谱性质的表征。结果表明,在与几种蛋白质(溶菌酶,胰岛素和β-2-微球蛋白)的淀粉样原纤维相互作用期间,该染料具有改变荧光光谱的能力。相反,这些蛋白质的单体形式没有引起明显的光谱变化。
