Synthetic peptides used in the study of amyloid-fibril like properties.

*The affinity for Congo red and green birefringence in polarized light was semiquantitatively estimated. -, no reaction; (+) partial weak reaction; + weak affinity and green birefringence. ++ strong affinity and bright green birefringence. **The strength of fluorescence after labeling with thioflavin S was semiquantitatively estimated. (+) partial weak reaction; + weak fluorescence; ++ strong bright fluorescence. ***Electron microscopy after that the peptides had been dissolved in dimethyl sulfoxide, diluted in water and incubated for 1 month.
