Abstract
This paper reports 50-s liquid chromatography (LC) separation of oxidative stress markers using an amide-modified pillar array column (PAC). The amide modification enables a sufficient retention of highly polar compounds under hydrophilic interaction LC (HILIC) conditions, and five fluorescence-labeled biothiols, i.e., cysteine, homocysteine, glutathione, cysteinylglycine, and N-acetylcysteine, in human plasma could be rapidly separated. Since these biothiols are associated with many diseases, this newly developed method could be a useful tool for the diagnosis or clinical investigation of biothiol-related diseases.
