[Gly22]-beta-Amyloid (1-42), E22G Arctic Mutation, Human

This is amino acids 1 to 40 fragment of the mutant form of beta-amyloid, with glycine substituted for glutamic acid at position 22 found in “Arctic” heredity. A toxic soluble beta-amyloid assembly (TA-beta) is formed more rapidly from 'Arctic' beta-amyloid than from wild-type beta-amyloid in the presence of liposomes containing GM1 ganglioside.
