Recombinant Expression And Purification Of Amyloid-Β In E. Coli, Wisam M. Beauti

Honors Theses

Alzheimer’s disease (AD) is a common neurodegenerative disorder that affects people older than 65 years 1,2,5. It is characterized by the presence of extracellular plaque deposits that are seen specifically in the brains of AD patients 4,5. These plaques are mainly comprised of amyloid-β (Aβ) peptide aggregates. Aβ plaque production and deposition is believed to drive AD pathogenesis. Studying these proteins is crucial to understanding aspects of AD in order to develop possible therapeutic treatments. Recombinant expression of Aβ can also provide a handle to introduce mutations in the protein to further study their structure-function relationships. However, synthetic Aβ monomer …
