Detection of Nitric Oxide and Superoxide Radical Anion by Electron Paramagnetic Resonance Spectroscopy from Cells using Spin Traps
Published on: August 18, 2012
Abstract:
A structure and magnetic parameters of a series of nitroxy and iminoxy radicals with different position of the phosphorus atom with respect to the radical center were established by means of EPR. Free radicals were obtained in the course of chemical and electrochemical reactions and also through UV-radiation with the use of "spin traps". The studied phosphorylated nitroxy and iminoxy radicals are revealed to be highly sensitive to the medium and temperature that makes them perspective "spin labels" in biological objects.
