Disclosed herein are antibodies that bind with high specificity to soluble oligomers of amyloid β (Abeta) and methods of employing those antibodies. The antibodies are able to distinguish between Alzheimer's Disease (AD) and control human brain extracts. The antibodies identify endogenous Abeta oligomers in AD brain slices and also bind to Abeta oligomers on cultured hippocampal cells. The antibodies neutralize endogenous Abeta oligomers and Abeta oligomers produced in solution.
A method for neutralizing the binding of soluble Abeta oligomers to cells comprising contacting soluble Abeta oligomers with a monoclonal antibody that selectively binds soluble 12-24 oligomers of Abeta 1-42 over trimers and tetramers of Abeta 1-42, and inhibits binding of soluble Abeta oligomers to cells, thereby neutralizing the binding of soluble Abeta oligomers to cells.
