About the EPR Laboratory
The Laboratory is equipped with 3 spectrometers (BRUKER) and home build sample holders (cavities) permitting X (9.5 GHz)- and Q (35 GHz)-bånd EPR, ENDOR (Electron Nuclear Double Resonance) and EIE (Endor Induced EPR) detections in the temperature interval 4 K - ca 400 K.
The operation of the laboratory is a collaboration between the Physics Department (UiO) and Department of Molecular Biology (UiO). The laboratory is a part of the Physics Department, in the research section Biophysics and Medical Physics (BMF), located in the 3rd floor in the Chemistry building.
