One feature of Alzheimer's Disease is the elevation of Aβ1-42 peptide. Here we provide a protocol for preparing synthetic Aβ1-42 oligomers, which impairs hippocampal Long-Term Potentiation, a cellular correlate of memory. This procedure is useful for investigating mechanisms of Aβ-induced pathology and drug screening.
