Images
Figure 1. The staining of Thioflavin S (in green) on adjacent sections of the hippocampus of a patient suffering from Alzheimer's disease. Thioflavin S binds both senile plaques (SP) and neurofibrillary tangles (NFT), the two characteristic cortical lesions of Alzheimer's. Amyloid beta is a peptide derived from the amyloid precursor protein which is only found in senile plaques, and so only plaques are visible in the right hand image.
