CeHR medium was originally formulated by Dr. Eric Clegg at the United States Army Center for Environmental Health Research to grow worms in an axenic liquid media. (http://usacehr.detrick.army.mil/CleggLab.html)

We are thankful to Eric for his invaluable help and advice through all the modifications we have since made to optimize CeHR medium to suit our research goals. We modified CeHR medium (mCeHR) because of our interests in defining the individual micronutrient components in order to identify the cellular and molecular components of metal homeostasis using C. elegans as a model multicellular eukaryote.
