Electron Paramagnetic Resonance Spectroscopy

Bruker E-Scan Table Top EPR spectrometer

Electron Paramagnetic Resonance Spectroscopy, also known as electron spin resonance or EPR, is based on absorption of microwave energy by free radicals or paramagnetic species in the presence of an external electromagnetic field, resulting in the transition of electron spin states.

This core facility within the UNMC Department of Cellular and Integrative Physiology houses a Bruker E-Scan Table Top EPR spectrometer.

In combination with EPR-detectable, radical-sensitive cyclic hydroxylamines – often referred to as “spin probes” – the E-Scan can be and has been used to measure levels of free radicals (e.g. superoxide, hydroxyl radical) in various biological samples including cultured cells, culture media, blood, and isolated tissue.
