Alkalmazás

Spin-label that has been used to study molecular migration and long-term stability of seeds and pollen. Has been covalently attached to oligonucleotides to prepare a DNA probe sensitive to electron spin resonance. The acetoxymethyl ester is an esterase-sensitive probe that crosses the blood-brain barrier for electron spin resonance-computed tomographic imaging.
Spin-label. The anionic form has been used to determine distribution coefficients of neutral solubilizates in anionic micelles.
Used in the preparation of a tetraphenylporphyrin bearing a nitroxyl radical.

Proton-electron double-resonance imaging (PEDRI) has considerable value for study of the distribution and elimination pathways of nitroxide free radicals (NFRs). This has been illustrated by its use in studies of kidney function in the living rat in which the NFR

The relations among hypertensive response, oxidative stress, and mitogen-activated protein kinase (MAPK) in cardiovascular tissues have not been fully established. We investigated the involvement of reactive oxygen species on changes in the hemodynamics and cardiovascular MAPKs activities induced by acutely

The relationship between molecular mobility (tauR) of the polar spin probe 3-carboxy-proxyl and water content and temperature was established in pea axes by electron paramagnetic resonance (EPR) and saturation transfer EPR. At room temperature, tauR increased during drying from 10(-11)
