LabArchives, a provider of online lab notebook software, and BioMed Central’s open access journal BMC Research Notes has published Mutagenetix, an online open access repository of ENU-generated data. The data is linked permanently to a ‘Data Note’, describing results from the ENU mutagenesis program, operated by the Beutler laboratory at The Scripps Research Institute in La Jolla, CA and which won them the Nobel Prize in Physiology or Medicine 2011.
