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.
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
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

A modification of a previously published method for analysis of total homocysteine in human serum is presented. The modification was implemented to allow use of a different derivatizing agent (i.e., 7-fluorobenzo-2-oxa-1,3-diazole-4-sulfonamide) which reacts much faster than the original derivatizing reagent
High-performance liquid chromatographic method to quantify total cysteine excretion in urine.
