Figures 1 and 2. Experimental data (in red) and SpinFit simulations (in blue) of two sets of DMPO radical adducts at a given time in the 2D field Web1 Sep 2001 · One of the most frequently used spin traps in free radical biology is 5,5-dimethyl-1-pyrroline N -oxide (DMPO). Despite its many successes, a major disadvantage with DMPO use in biological systems is that the DMPO-superoxide adduct spontaneously decays to the DMPO-hydroxyl adduct [19]. jetblue flights to santiago
Generation of thiyl radical by nitric oxide: a spin trapping study
Web1 May 2007 · The formation of the radical spin adducts, DMPO-S-G or DEPMPO-S-G, was monitored with ESR spectrometer (JES-RE-1X, JEOL Ltd., Japan) operating at X-band (9.43 GHz), a microwave power of 10 mW, 100 kHz field modulation and 0.2 or 0.063 mT modulation width. A range of external magnetic field of 15 mT was swept at a scan rate of … Web1 Nov 1994 · In the absence of DMPO, molecular oxygen is consumed by a sequence of reactions initiated by the glutathione thiyl radical. Similarly, the estradiol phenoxyl radical abstracts hydrogen from reduced β-nicotinamide-adenine dinucleotide (NADH) to generate the NAD· radical. Web1 Oct 1996 · Abstract.
