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...

Rotational correlation times of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin label with respect to heme and nonheme proteins.

Biomacromolecules 4(6) , 1630-5, (2003)

Noncovalent spin labeled proteins (ovalbumin, bovine serum albumin, hemoglobin, and cytochrome c) were investigated in order to follow the different type of interactions between the nitroxide radical of 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy spin ...

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...

Raman and surface enhanced Raman spectroscopy of 2,2,5,5-tetramethyl-3-pyrrolin-1-yloxy-3-carboxamide labeled proteins: bovine serum albumin and cytochrome c.

Biopolymers 62(6) , 341-8, (2001)

2,2,5,5-Tetramethyl-3-pyrrolin-1-yloxy-3-carboxamide (tempyo) labeled bovine serum albumin and cytochrome c at different pH values were prepared and investigated using Raman-resonance Raman (RR) spectroscopy and surface enhanced Raman scattering (SERS) spectr...

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...

Free radical imaging by electron spin resonance computed tomography in rat brain.

Brain Res. 697(1-2) , 44-7, (1995)

Images of nitroxide radicals were obtained from the brains of living rats following intracarotid injection of imaging agent, [2-(14-carboxytetradecyl)-2-ethyl-4,4-dimethyl-3-oxazolidinylox y] (16 DS) using L-band electron spin resonance computed tomography (E...

ESR imaging on a solid-tumor-bearing mouse using spin-labeled dextran.
