General description

Thioflavine S aids in staining and visualizing β-amyloid plaques in Alzheimer′s disease. Thioflavin S binds to fibrillar β-amyloid plaques, and does not diffuse in the plaques. Thioflavin-S staining aids in visualizing smaller plaques throughout the neocortex, hippocampus and thalamic region.

Application

Thioflavine S has been used to stain and visualize β-amyloid structures in the tissue sections.
