Illustration：This42-residue fragment of amyloid β-protein has been found to be a majorconstituent of the senile plaques formed in the brains of patients withAlzheimer's disease and late Down's syndrome. Aβ 1-42 readily forms neurotoxicoligomers at physiological pH. The peptide has been used to detect amyloidβ-protein multimers in the cerebrospinal fluid of Alzheimer's disease patientsthrough fluorescence correlation spectroscopy. For detailed descriptions of thepreparation of Aβ 1-42 monomers and protofibrils please see the paper of Jan,Hartley, and Lashuel.
