Oxidase method
WebGlucose (glucose oxidase method) This procedure, taking advantage of the specificity of glucose oxidase, is based upon the conversion of glucose to gluconic acid and hydrogen peroxide by glucose oxidase and the subsequent oxidation of o-dianisidine to its oxidized form, measurable at 420 nm, by hydrogen peroxide with peroxidase. WebUnit definition of glucose oxidase = One unit will oxidize 1.0 μMol of β-D-glucose to D-gluconolactone and H 2 O 2 per minute at pH 5.1 at 35 °C (equivalent to an O 2 uptake of 22.4 μL per minute). If the reaction mix is saturated with oxygen, the activity may increase by up to 100%. 4. Discussion. β -D-Glucose + O2 + H 2 O GO > D-Glucono ...
