image: The anti-beta-amyloid monoclonal antibody 6E10 could recognize all types of Aβ42, but clone 10A1 and 11F5 only bound to tetramers and octamers. The helper phage M13K07 was used as a negative control. view more

Earlier amyloid-beta assemblies may be one of the most important causes of Alzheimer's disease. Passive immunization of anti-amyloid-beta antibodies can reduce amyloid-beta burden and improved memory performance in various Alzheimer's disease animal models or patients. Screening humanized antibodies from a human Fab phage display library is an effective and quick method to obtain beta-amyloid oligomers. Thus, a recent study published in the Neural Regeneration Research (Vol. 8, No. 33, 2013) successfully constructed a naïve human Fab library and obtained a human Fab antibody and a single-domain antibody that specifically recognized amyloid-beta (Aβ)42 oligomers.
