(Glu20) -Amyloid β-Protein (1-42)

(Glu20) -Aβ42 is a slowly fibrillizing variant of amyloid-β, the primary component of Alzheimer's disease plaques. This mutation reduces aggregation propensity, making it a critical tool for in vitro and in vivo studies investigating Aβ aggregation kinetics, neurotoxicity, and therapeutic intervention strategies.
