Congo red binding absorption spectra of HEWL in the absence and presence of taxifolin.

<p>Protein samples (50 μM) were incubated in 50 mM glycine (pH 2.2) at 57°C either alone (●) or with 25 (○), 50 (♦), or 100 (◊) μM taxifolin for 7 days. Congo red absorbance alone and in the presence of HEWL monomer are indicated by (△) and (▲), respectively.
