Curcumin as an amyloid-indicator dye in E. coli

Oscar A. McCrate, Xiaoxue Zhou, Lynette Cegelski

Research output: Contribution to journalArticlepeer-review


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.
