An enzymatic spectrophotometric method for the determination of xanthine and hypoxanthine.

چکیده
A method for determining the total content of the oxypurines xanthine and hypoxanthine in urine is described which is technically simplified and has greater specificity than existing methods. This method is highly specific, reproducible, and accurate. It also allows an estimation of the present xanthine and hypoxanthine in the urine without performing any additional measurements.When applied to plasma, special concentrating proceduresare required and the method is therefore lessprecise.

متن کاملKinetic determination of serum adenosine deaminase.
A new kinetic method for the determination of serum adenosine deaminase (EC 3.5.4.4) is described, with adenosine as the substrate and nucleoside phosphorylase and xanthine oxidase as the reaction enzymes. Inosine is produced, which is converted to hypoxanthine. The hypoxanthine is oxidized to xanthine, which is further oxidized to uric acid. In these two reactions, blue 2,6-dichlorophenolindop...
متن کاملA colorimetric assay for xanthine oxidase in rat liver homogenates.
In studying the oxidation of xanthine manometrically by using liver homogenate systems (l), certain irregularities in the method have become evident to the authors. Occasionally an oxygen consumption has been observed after 2 to 3 hours of incubation which is greatly in excess of the theoretical requirement for the complete oxidation of the xanthine substrate. In certain experiments the measure...
متن کاملEnzymatic colorimetric method for the determination of inorganic phosphorus in serum and urine.
The performance of an enzymatic colorimetric method for the determination of inorganic phosphorus in serum and urine is described. Phosphate ions react with inosine in the presence of purine nucleoside phosphorylase to form hypoxanthine; this is oxidized by xanthine oxidase to uric acid with production of hydrogen peroxide. The latter is determined with the aid of the chromogen system peroxidas...
متن کاملDetermination of Xanthine in the Presence of Hypoxanthine by Adsorptive Stripping Voltammetry at the Mercury Film Electrode
A stripping method for the determination of xanthine in the presence of hypoxanthine at the submicromolar concentration levels is described. The method is based on controlled adsorptive accumulation at the thin-film mercury electrode followed by a fast linear scan voltammetric measurement of the surface species. Optimum experimental conditions were found to be the use of 1.0 × 10(-3) mol L(-1) ...
