The hydroxyl radical adducts of 5,5 dimethyl-1-pyrolline-N-oxide (DMPO) and 3,3,5,5 tetramethyl-1-pyrolline-N-oxide (TMPO) formed in the presence of hydrogen peroxide and FeII are normally quite stable, but in the presence of 5-20 micromolar myoglobin their ESR signals decay rapidly. This decay

To obtain the strongest possible free radical spin adduct signal using the electron paramagnetic resonance spectroscopy-spin trapping technique, it is desirable to load an animal with the highest dose of spin trap possible. One hundred and twenty six male Sprague-Dawley

The roles of oxygen and reactive oxygen intermediates in apoptosis are unclear at present. Although oxygen and reactive oxygen intermediates are not required for the execution of apoptosis, oxygen may be involved in at least some forms of apoptosis. In

A new approach for in vivo spin trapping and quantitation of oxygen-derived free radicals has been developed using a continuous flow high speed ESR detection system. Spin adducts of OH. were detected as 1:1:1:1:1:1 sextets (aN=15.2 G, aH=16.8 G, g=2.0055)

When aqueous solutions of the spin trap 5,5'-dimethyl-1-pyrroline-N-oxide (DMPO) are treated with hydrogen peroxide in the presence of either FeII or light, the hydroxyl radical adduct DMPO-OH is formed, with a characteristic 4 line ESR spectrum. When oxy- or metmyoglobin
