Immunologic Properties of Glucose Oxidase
The Journal of Immunology, 1970Abstract Glucose oxidase, an anzyme obtained from Aspergillus niger, is a potent antigen. Guinea pigs and rabbits immunized with this antigen in complete Freund's adjuvant produced high serum concentrations of precipitating antibody. In addition, heat-inactivated enzyme and apoenzyme can be used to detect cellular immunity in the guinea ...

Glucose‐Sensitive Liposomes Incorporating Hydrophobically Modified Glucose Oxidase
Lipids, 2008AbstractGlucose‐sensitive liposomes were prepared by incorporating hydrophobically modified glucose oxidase (EC 1.1.3.4.) into the liposomal bilayer of dioleoylphosphatidylethanolamine and cholesteryl hemisuccinate. For the release test, calcein, a fluorescence marker, was entrapped in the liposomes.

Calorimetric Glucose Determination by Glucose Oxidase —Methylene Blue
Acta Biotechnologica, 1982AbstractThe reaction between glucose and methylene blue, catalyzed by glucose oxidase (GOD)was analysed calorimetrically.The amount of heat produced under saturating methylene blue concentrations ( > 10−2 mol/1)was measured with glucose concentration and time as parameters (kinetic procedure) Kinetic constants (pseudo one substrate kinetics) were ...

Glucose oxidase of Phanerochaete chrysosporium
1988Publisher Summary Glucose oxidase catalyzes the oxidation of D-glucose to δ-D-gluconolactone and H 2 O 2 in the presence of molecular oxygen. In a subsequent step δ -D-gluconolactone is nonenzymatically hydrolyzed to D-gluconic acid. This enzyme has been demonstrated in various Aspergillus and Penicillium species and has recently been purified ...

Glucose Biosensor Using Glucose Oxidase Immobilized in Polyaniline
Applied Biochemistry and Biotechnology, 1992A biosensor for glucose utilizing kinetics of glucose oxidase (EC 1.1.3.4.) was developed. The enzyme was immobilized on polyaniline by covalent bonding, using glutaraldehyde as a bifunctional agent. The system showed a linear response up to 2.2 mM of glucose with a response time of 2.5-4.0 min. In addition, the immobilized enzyme had a higher activity

Glucose Oxidase Multilayer Modified Microcantilevers for Glucose Measurement
Analytical Chemistry, 2005We report a novel enzyme-based microcantilever sensor by using layer-by-layer nanoassembly modification. A glucose oxidase (GOx) functionalized microcantilever underwent bending when it was exposed to glucose solutions. The magnitudes of bending were proportional to the concentrations of glucose.

Glucose oxidase immobilized polyethylene‐g‐acrylic acid membrane for glucose oxidase sensor
Biotechnology and Bioengineering, 1990AbstractA polyethylene‐g‐acrylic acid (PE‐g‐AA) graft copolymer was prepared via gamma‐ray‐irradiation‐induced postirradiation procedures, and was used as support material for the immobilization of glucose oxidase. Soluble carbodiimides were used as the coupling agent. Reasonable yields were obtained with CMC but not with EDAC, EEDQ, or WRK.

Glucose sensor with immobilized glucose oxidase-glucose isomerase membrane
Journal of Molecular Catalysis, 1981Abstract A glucose sensor, i.e., an oxygen detection electrode with immobilized glucose oxidase, has been studied by several researchers as a novel analytical technique which can simplify tedious steps in conventional methods of glucose determination. In a glucose sensor of such construction, any glocuse oxidase inhibition will impair the performance

Glucose concentration measurement using immobilized glucose oxidase
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1989Abstract A reactor with an immobilized glucose oxidase layer on a magnetic disc impeller for routine determination of the glucose concentration in biological samples was designed and studied both experimentally and theoretically. The rate of oxygen concentration decrease in the reacting mixture (consisting of ca.
