iLab Operations Software Support will be staffed at reduced levels during the week Feb. 25 - Mar 1. iLab Support will prioritize critical issues (i.e. issues that prevent key workflows from completing). Regular support tickets will be monitored periodically. To escalate an issue, please add "Urgent" to the ticket / email subject or if dialling the iLab support phone press "1" when prompted (regional specific numbers can be found here). You can also refer to the iLab Help Site and iLab Status Page for site information.

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.
