This article describes a protocol for visualizing amyloid Aβ plaques in Alzheimer's disease mouse models using methoxy-X04, which crosses the blood-brain barrier and selectively binds to β-pleated sheets found in dense core Aβ plaques. It allows pre-screening of plaque-containing tissue sections prior to immunostaining and processing for electron microscopy.
