(Gly22) -amyloid beta-protein (1-40)

This research-grade peptide is the Arctic variant (E22G) of amyloid-β (1-40), where a glycine substitution at position 22 enhances its aggregation propensity. It is extensively used in both in vitro and in vivo studies to investigate the mechanisms of oligomer formation and toxicity in Alzheimer's disease pathology.
