Immobilized Glucose Oxidase in the Potentiometric Detection of Glucose
Applied Biochemistry and Biotechnology, 1984Previous work has shown that glucose oxidase can be immobilized on platinum to give an electrode that responds potentiometrically to glucose over the clinically useful range of about 10-250 mg glucose/100 mL. The present studies were carried out with electrochemically pretreated platinum and with gold or porous graphite substituted for the platinum ...

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 ...

Inkjet delivery of glucose oxidase
Chemical Communications, 2010The activity of glucose oxidase is reduced by inkjet printing and is a function of the printing conditions. Standard characterisation methods show no significant change to enzyme molecular weight, secondary structure and general molecular shape as a function of printing parameters.

Effects of glucose oxidase in mice
Biochemical Pharmacology, 1964Abstract The effects of glucose oxidase, which oxidizes glucose and produces H2O2, were studied in mice after intraperitoneal injection of supralethal doses of the enzyme. Such injections cause the appearance of hematin pigment in the plasma, up to 20 per cent of this pigment being methemoglobin.

Some studies of glucose oxidase
Archives of Biochemistry and Biophysics, 1961Abstract A commercial preparation of glucose oxidase is shown to oxidize d -glucose, d -galactose, d -mannose, and d -xylose at relative rates which are pH dependent. The product of these reactions is the corresponding glyconic acid which in each case is identified as the crystalline γ-lactone and amide.

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 ...

Studies on conditions for the polarographic determination of glucose with glucose oxidase
Clinica Chimica Acta, 1972Abstract Results are presented on the effect of several variables on a method for the determination of glucose using a polarograph with a Clark-type O 2 electrode and glucose oxidase. Glucose concentration [ G ] was proportional to the rate of O 2 consumption |− Δ O 2 / Δt | in the 5–800 μg/ml range.

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 ...

The characterization of liposomal glucose oxidase electrodes for the measurement of glucose
Biosensors and Bioelectronics, 1995Many biosensors have been described for the measurement of glucose in order to monitor diabetic patients. Glucose oxidase has been used commonly in the construction of glucose sensors but the performance of this enzyme is limited by enzyme saturation kinetics, which restrict the measurement of clinically relevant glucose concentrations (0 to 25 mM ...
