Figure 2. Far-UV circular dichroism spectra.

Figure 2

(A) hIAPP; (B) hIAPP with equimolar BPA; (C) hIAPP with 5-fold BPA. hIAPP was dissolved in HFIP first and then diluted to a final concentration of 15 µM. The presence of BPA promoted structural transition to β-rich structures. The spectra were record in the PBS buffer in a timeframe of 24 h.
