Abstract
We have demonstrated that curcumin is an amyloid-specific dye in E. coli. Curcumin binds to curliated whole cells and to isolated curli amyloid fibers. Similar to Congo red, curcumin exhibits a red-shift in absorbance and a significant increase in fluorescence upon binding to isolated curli.
摘要
我们已经证明姜黄素是大肠杆菌中一种淀粉样蛋白特异性染料。姜黄素与卷曲菌全细胞和分离的卷曲菌淀粉样纤维结合。与刚果红类似，姜黄素与分离的卷曲菌结合时，其吸收光谱发生红移，荧光显著增强。
