Figure 2. Effects of quinones on amyloid formation of insulin.

(A) Relative ThT fluorescence of insulin in the presence or absence of simple quinones; (B) Relative ThT fluorescence of insulin in the presence or absence of anthraquinone derivatives from rhubarb, AQ was used as a control; (C) Relative ThT fluorescence of pre-incubated insulin with quinones treatments start at 9 h or 27 h, the arrows indicate the quinones adding points.
