α-Synuclein (61-95) (human)
α-synuclein (61-95) has originally been isolated from the insoluble core of Alzheimer's disease (AD) amyloid plaque. Synonyms: H-Glu-Gln-Val-Thr-Asn-Val-Gly-Gly-Ala-Val-Val-Thr-Gly-Val-Thr-Ala-Val-Ala-Gln-Lys-Thr-Val-Glu-Gly-Ala-Gly-Ser-Ile-Ala-Ala-Ala-Thr-Gly-Phe-Val-OH; NAC; Non-Aβ Component of Alzheimer's Disease Amyloid. CAS No. 154040-19-4. Molecular formula: C141H235N39O49. Mole weight: 3260.61.
α-Synuclein (67-78) (human)
The Parkinson's disease-associated protein α-synuclein (α-syn) is not only expressed in the cytoplasm of neurons, but also secreted in the extracellular space and internalized into glial cells through a lipid raft dependent process. The tilted peptide α-synuclein(67-78) has a high affinity with cholesterol and is toxic to cultured astrocytes. The glycosphingolipid-binding domain of alpha-synuclein (34-45) encapsulates a cholesterol-recognition consensus motif with a low affinity and no toxicity. Synonyms: α-syn (67-78) (human); H-Gly-Gly-Ala-Val-Val-Thr-Gly-Val-Thr-Ala-Val-Ala-OH; L-Alanine, glycylglycyl-L-alanyl-L-valyl-L-valyl-L-threonylglycyl-L-valyl-L-threonyl-L-alanyl-L-valyl-.

α-Synuclein (71-82) (human)
