Automatic Translation

Herein we report a tailored HPLC purification protocol that yields high-purity amyloid beta 42 (Aβ42) and amyloid beta 40 (Aβ40) peptides, capable of oligomer formation. Amyloid beta is a highly aggregation prone, hydrophobic peptide implicated in Alzheimer's disease. The amyloidogenic nature of the peptide makes its purification a challenge.
