Journal of pharmaceutical and biomedical analysis, 10(10-12), 985-988 (1992-10-01)
The present investigation analyses the potentials of capillary chromatography using packed fused silica capillaries filled with 5 microns RP-18 for the fluorescence determination of glutathione in human blood samples. Adaptation of conventional HPLC equipment for miniaturized chromatographic assays proved successful.

A semi-micro column HPLC-fluorescence method for routine determination of thiol derivatives such as homocysteine (Hcy), cysteine (Cys) and cysteamine (CA) is described. The thiol derivatives labeled with ammonium-7-fluorobenzo-2-oxa-1,3-diazole-4-sulfonate (SBD-F) were isocratically separated within 12 min on a semi-micro ODS column

The recognition of homocysteine as a vascular risk factor has led to increased clinical interest in assaying plasma homocysteine concentrations. Our aim was to improve the reliability of a widely used assay based on HPLC of the fluorescent 7-benzo-2-oxa-1, 3-diazole-4-sulfonic

The analytical method was optimized for L-cysteine (Cys) in rat plasma with co-existing L-cystine (Cyss). We observed that more than 100% Cyss in rat plasma was converted to Cys under typical conditions for the conversion with 7-fluoro-2,1,3-benzoxadiazole-4-sulfonate (SBD-F). Another conversion

A sensitive HPLC-fluorescence method for determining total endogenous plasma homocysteine (Hcy), cysteine (Cys) and cysteinylglycine (Cys-Gly) following derivatization with ammonium 7-fluoro 2,1,3-benzoxadiazole-4-sulphonate (SBD-F) is described. Quantitation utilizes an internal standard, 2-mercaptoethylamine. The derivatization procedure has been optimized for concentration of
