Comparison of N-ethyl maleimide and N-(1-phenylethyl) maleimide for derivatization of biological thiols using liquid chromatography-mass spectrometry

Author(s): Russo MST; Napylov A; Paquet A; Vuckovic D;

The ratio between reduced and oxidized thiols, mainly glutathione and oxidized glutathione, is one of the biomarkers for the evaluation of oxidative stress. The accurate measurement of thiol concentrations is challenging because reduced thiols are easily oxidized during sample manipulation. Derivatization is commonly used to protect thiols from oxidation. ...
