Analytical methods to measure plasma total homocyst(e)ine (tHcy) concentrations are reviewed. High-pressure liquid chromatography (HPLC) with fluorometric detection is the most widely used method to determine plasma tHcy concentrations. Both monobromobimane and ammonium 7-fluorobenzo-2-oxa-1,3-diazole-4-sulphonate (SBD-F) are popular thiol-specific fluorogenic agents

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

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
