Interlaboratory comparison of enzymatic methods for serum glucose determination.
This report describes an interlaboratory comparison of enzymatic serum glucose methods as currently applied in several instrumental adaptations. Four spectrophotometric, hexokinase-based methods used with the Du Pont "aca," the Abbott "Bichromatic Analyzer," the Aminco "Rotochem," and the Technicon "AutoAnalyzer ll" were compared with glucose oxidase-based methods as used with the Beckman "Gluc...
متن کاملElectrochemical-Enzymatic Determination of Glucose in Beverages
This laboratory seeks to quantitatively determine glucose concentration in common beverages. The method employed is enzyme catalyzed oxidation of glucose, quantified by chronoamperometry. With an inexpensive patterned electrode and low cost glucose oxidase enzyme, an electrochemical sensor is constructed to selectively measure glucose in complicated beverages which can present as analytically c...
متن کاملEnzymatic determination of sodium in serum.
This is a kinetic assay for measuring serum Na+ concentration based on determination of Na+-dependent beta-galactosidase (EC 3.2.1.23) activity. The method, sufficiently sensitive to measure sub-millimolar concentrations of Na+, was modified by including a Na+-binding agent (cryptand) to provide a linear assay for serum Na+ concentrations between 110 and 160 mmol/L. The assay was developed with...
متن کاملEnzymatic determination of D-mannose in serum.
A new and simple enzymatic assay for measuring D-mannose in serum is described. Endogenous glucose is eliminated from serum by use of glucose oxidase (EC 1.1.3.4) and catalase (EC 1.11.1.6). D-Mannose concentration is calculated from the increase in NADH formation after mannosephosphate isomerase (EC 5.3.1.8) is added. This increase is a result of coupling the following series of enzymes: hexok...
