Application: Beta-Amyloid (20–42) is a synthetic peptide fragment corresponding to the hydrophobic C-terminal region of amyloid-β. This region plays a critical role in peptide aggregation, fibril formation, membrane interaction, and cytotoxicity. Due to its strong aggregation propensity, Aβ(20–42) is commonly used as a model system for investigating structural determinants of amyloid assembly and fibrillogenesis. Beta-Amyloid (20–42) supports biophysical studies, aggregation inhibitor screening, membrane interaction assays, and mechanistic research into Alzheimer’s disease amyloid pathology. It is valuable for exploring how C-terminal amyloid sequences drive neurotoxic peptide assembly.
