Congo-Red (CR) binding to different HET-s IBs by UV/Vis spectroscopy and staining and birefringence under cross-polarized light using an optic microscope. (A and B) CR spectral changes in the presence of different HET-s IBs; (A) Changes in λmax and intensity in CR spectra in the presence of IBs; (B) Difference absorbance spectra of CR in the presence and absence of IBs showing in all cases the characteristic amyloid band at ~540 nm. (C) HET-PFD IBs stained with Congo red and observed at 40× magnification and in (D) the same field observed between crossed polarizers displaying the green birefringence characteristic of amyloid structures.
