Swiss Prot P05067
Scientific Background Our amyloid beta oligomer antibody (clone 1C1) has been tested for specificity against synthetic AB 1-42 aggregates, with higher specificity to oligomers demonstrated. In the brain, amyloid beta peptide (Aβ) is generated by protease cleavage of amyloid precursor protein (APP), which aggregates into oligomers, protofibrils, fibrils and ultimately plaques in neurodegenerative diseases. The accumulation of Aβ plaques in the brain is considered a hallmark of Alzheimer’s disease (AD), and most of the drugs tested for AD in the past 20 years have targeted amyloid beta accumulation (1). The immunogen used was our Amyloid Beta 1-42 (Aβ42) Oligomers are generated from Amyloid Beta Peptide 1-42 pre-treated with 1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) as previously published (2,3).
