The amyloid-β (Aβ)-injected animal model enables the administration of a defined quantity and species of Aβ fragments and reduces individual differences within each study group. This protocol describes the intracerebroventricular (ICV) injection of Aβ without stereotactic instruments, enabling the production of Alzheimer-like behavioral abnormalities in normal mice.

This manuscript describes standard protocols for measuring tau hyperphosphorylation, measuring tau binding to microtubules, and localization of intracellular tau following drug treatments. These protocols can be used repetitively for screening drugs or other compounds that target tau hyperphosphorylation or microtubule binding.
