The Flemish mutation (A21G) displays a decreased tendency to aggregate and a reduced neurotoxicity. A21G is pathogenic because it is degraded by Neprilysin significantly more slowly than WT Abeta42. Synonyms: Amyloid β-Protein (1-42) A21G; H-Asp-Ala-Glu-Phe-Arg-His-Asp-Ser-Gly-Tyr-Glu-Val-His-His-Gln-Lys-Leu-Val-Phe-Phe-Gly-Glu-Asp-Val-Gly-Ser-Asn-Lys-Gly-Ala-Ile-Ile-Gly-Leu-Met-Val-Gly-Gly-Val-Val-Ile-Ala-OH; L-alpha-aspartyl-L-alanyl-L-alpha-glutamyl-L-phenylalanyl-L-arginyl-L-histidyl-L-alpha-aspartyl-L-seryl-glycyl-L-tyrosyl-L-alpha-glutamyl-L-valyl-L-histidyl-L-histidyl-L-glutaminyl-L-lysyl-L-leucyl-L-valyl-L-phenylalanyl-L-phenylalanyl-glycyl-L-alpha-glutamyl-L-alpha-aspartyl-L-valyl-glycyl-L-seryl-L-asparagyl-L-lysyl-glycyl-L-alanyl-L-isoleucyl-L-isoleucyl-glycyl-L-leucyl-L-methionyl-L-valyl-glycyl-glycyl-L-valyl-L-valyl-L-isoleucyl-L-alanine.

(Gly22)-Amyloid β-Protein (1-40)
(Gly22)-Amyloid β-Protein (1-40) is a highly neurotoxic Aβ arctic mutant (E22G) that has been used to study the mechanism underlying of soluble and insoluble β-amyloid aggregation formation. As wild-type Aβ, it preferably assembles in the presence of GM1 ganglioside. Synonyms: Amyloid β-Protein (1-40) E22G; H-Asp-Ala-Glu-Phe-Arg-His-Asp-Ser-Gly-Tyr-Glu-Val-His-His-Gln-Lys-Leu-Val-Phe-Phe-Ala-Gly-Asp-Val-Gly-Ser-Asn-Lys-Gly-Ala-Ile-Ile-Gly-Leu-Met-Val-Gly-Gly-Val-Val-OH; L-alpha-aspartyl-L-alanyl-L-alpha-glutamyl-L-phenylalanyl-L-arginyl-L-histidyl-L-alpha-aspartyl-L-seryl-glycyl-L-tyrosyl-L-alpha-glutamyl-L-valyl-L-histidyl-L-histidyl-L-glutaminyl-L-lysyl-L-leucyl-L-valyl-L-phenylalanyl-L-phenylalanyl-L-alanyl-glycyl-L-alpha-aspartyl-L-valyl-glycyl-L-seryl-L-asparagyl-L-lysyl-glycyl-L-alanyl-L-isoleucyl-L-isoleucyl-glycyl-L-leucyl-L-methionyl-L-valyl-glycyl-glycyl-L-valyl-L-valine. Grades: ≥95%. CAS No. 175010-18-1. Molecular formula: C191H291N53O56S. Mole weight: 4257.74.
