Alternative Name: apoE(133-149)

Biological Activity

Apolipoprotein (ApoE) peptide fragment that functions via the low-density lipoprotein receptor-related protein (LRP). Substantially reduces the symptoms of experimental autoimmune encephalomyelitis, a model of human multiple sclerosis, and suppresses inflammation, demyelination and infiltration of cells into the spinal cord. Also acts as a non-competitive antagonist at α7 nicotinic acetylcholine receptors (IC50 = 445 nM).

Technical Data


(Modifications: Leu-1 = N-terminal Ac, Leu-17 = C-terminal amide)

Soluble to 1 mg/ml in water
Store at -20°C
