Lab Website

Esther Oh Lab

  • The Esther Oh Lab is interested in developing biological markers for pre-clinical stages of Alzheimer's disease (AD). Our current research involves using transgenic models of AD to develop peripheral injections of monoclonal antibodies against amyloid-beta as a tool to detect a level of amyloid-beta that would be correlative to the amyloid-beta level in the brain.
