W-band frequency-swept EPR.
J. Magn. Reson. 205(1) , 93-101, (2010) This paper describes a novel experiment on nitroxide radical spin labels using a multiarm EPR W-band bridge with a loop-gap resonator (LGR). We demonstrate EPR spectroscopy of spin labels by linear sweep of the microwave frequency across the spectrum. The hig... |

Assignment of proton endor resonances of nitroxyl spin-labels in frozen solution.
Free Radic. Res. Commun. 10(1-2) , 95-101, (1990) Spin-label nitroxyl derivatives of tetramethylpyrroline and tetramethylpyrrolidine in frozen solutions of perdeuterated methanol have been characterized by electron nucleus double resonance (ENDOR spectroscopy). With use of selectively deuterated derivatives ... |

Effects of inspired oxygen concentration on in vivo redox reaction of nitroxide radicals in whole mice.
Biochem. Biophys. Res. Commun. 182(3) , 1108-14, (1992) Effects of inspired oxygen concentration on metabolism of nitroxide radical were measured in whole mice by using in vivo ESR. Oxygen concentration influenced spin-clearance of nitroxide differently in abdomen and head, suggesting that either O2 concentrations... |

Radical scavenger can scavenge lipid allyl radicals complexed with lipoxygenase at lower oxygen content.
Biochem. J. 395(2) , 303-9, (2006) Lipoxygenases have been proposed to be a possible factor that is responsible for the pathology of certain diseases, including ischaemic injury. In the peroxidation process of linoleic acid by lipoxygenase, the E,Z-linoleate allyl radical-lipoxygenase complex ... |

Quantification of lipid alkyl radicals trapped with nitroxyl radical via HPLC with postcolumn thermal decomposition.
J. Lipid Res. 46(11) , 2506-13, (2005) Lipid alkyl radicals generated from polyunsaturated fatty acids via chemical or enzymatic H-abstraction have been a pathologically important target to quantify. In the present study, we established a novel method for the quantification of lipid alkyl radicals... |

EPR study of non-covalent spin labeled serum albumin and hemoglobin.
Biophys. Chem. 99(2) , 181-8, (2002) Electron Paramagnetic Resonance (EPR) was used to investigate the Tempyo spin label (3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy) as a report group for the interactions and the conformational changes of lyophilized bovine serum albumin (BSA) and bovine... |

ESR imaging on a solid-tumor-bearing mouse using spin-labeled dextran.
Biosci. Biotechnol. Biochem. 65(4) , 787-94, (2001) Imaging of a tumor with ESR was tried using two different types of spin probes, a low molecular weight spin probe, CPROXYL, and a polymer spin probe, TEMPO-DX. Spin probes were administered to a mouse bearing a solid tumor that was a transplanted Ehrlich's as... |
