Intrinsic Buffer Hydroxyl Radical Dosimetry for Hydroxyl Radical Protein Footprinting
, 2020 Hydroxyl radical protein footprinting (HRPF) coupled to mass spectrometry is a powerful technique for the analysis of protein topography as it generates covalent mass labels that can survive downstream sample handling, and it is sensitive to the solvent ...

Theoretical studies on the reaction mechanism of 1-chloroethane with hydroxyl radical
, 2007 The reaction mechanism of 1-chloroethane with hydroxyl radical has been investigated by using density functional theory (DFT) B3LYP/6-31G (d, p) method. All bond dissociation enthalpies were computed at the same theoretical level.

Measurement of intracellular hydroxyl radical concentration.
, 2012 The HM1070 (green) and ΔasrR (yellow) intracellular hydroxyl radical concentration was quantified by measuring the fluorescence intensity of a ROS-specific probe on cells under unstressed conditions or following a 10-min treatment with 0.5 mM or 2 mM of ...

Hydroxyl radical formation in human gastric juice
, 1992 The hydroxyl radical is the most potent free radical derived from oxygen, and has been implicated in damage caused to the gastroduodenal mucosa. The ability of human gastric juice to generate hydroxyl radicals has been investigated in 54 adults with ...
