Congo-red stains demonstrated a marked absorption of the dye by some of this material. Figure 1 Biopsy of the Trachea in Case 1, Taken at Bronchoscopy, Showing Submucosal Infiltration of Amyloid.

The latter can be identified histologically with dyes such as Congo Red and thioflavin ... most exciting and rapidly progressing research on amyloid therapeutics. Two main approaches are being ...

Amyloid proteins and peptides are associated ... An example of a compound that can do this is the Congo red dye used to stain amyloids that form in nematodes used for research.
