Selection of Aptamers for Amyloid β-Protein, the Causative Agent of Alzheimer's Disease

Overview

Aptamers are short ribo-/deoxyribo-oligonucleotides selected through in-vitro evolution methods for their affinity to specific targets. This study demonstrates the selection of aptamers for amyloid β-protein, which is linked to Alzheimer's disease.

Key Study Components
