RI-OR2

Catalog No.: A78407
Amyloid-β Oligomerization Inhibitor
RI-OR2 is an amyloid-β (Aβ) oligomerization inhibitor that functions as a retro-inverso peptide. It has been shown to bind effectively to immobilized β-Amyloid (1-42) monomers and fibrils, demonstrating an apparent dissociation constant (Kd) of 9-12 μM. Additionally, RI-OR2 inhibits the extension of Aβ(1-42) fibrils, making it a valuable tool for research into Alzheimer’s disease and the mechanisms of amyloid pathology.
