On Thursday June 27th, 2019 at 5:00 AM (U.S. EST) Agilent Site Reliability Engineers will be working with our Network Service Provider to upgrade the API server for the North American instance. The entire process is expected to be 1 hour, and iLab customers using the API for any features may experience a decrease in performance during this time. More information can be found on the iLab Status Site. For any questions, please contact iLab Support at or by clicking on the 'Help' link at the top of your account page.

VUMC FRIM Core (Free Radicals in Medicine)

Overview of Services

The Free Radicals in Medicine Core, FRIMCORE, provides site-specific, selective and reliable measurements of reactive oxygen species (ROS) such as superoxide radical (O2•), hydrogen peroxide (H2O2), nitric oxide (NO•) and peroxynitrite (ONOO−) and various free radical intermediates in cells and tissue for investigators at the Vanderbilt Campus and beyond. Major resources are the Electron Spin Resonance spectrometer (ESR) and HPLC system for quantitative superoxide measurements using spin traps, spin probes, fluorescent probes dihydroethidium and MitoSOX. We are located on the fifth floor of the Preston Research Building. The facility is available to all Vanderbilt faculty and other interested parties. We provide assistance with ROS measurements and consultations for ROS-related studies.
