DETAILS

Sigma Aldrich - 215430

Application
Spin trap reagent used to measure ethanol oxidation to 1-hydroxyethyl radical (HER) which can bind to protein. Has also been used in studies of DNA methylation, iron-mediated polyunsaturated fatty acid peroxidation, and free-radical formation by Alzheimer β-amyloid peptide. The formation of hydroxyl radical in chondrocytes and cartilage has been detected using POBN.
Spin-trap suitable for detecting hydroxyl radicals1 and selenide radical anions.2
Packaging
1 g in glass bottle
