Description
Since its discovery as an "antibiotic" (shown subsequently to be due to peroxide formation) there has been an interest in glucose oxidase, chiefly because of its utility in glucose estimation. For most clinical work the crude form of the A. niger enzyme has been satisfactory. However, it contains trace amount of polysaccharidases such as amylase, maltase and sucrase which can contribute to falsely high glucose levels. The purified enzyme is free of these traces and is recommended for analytical use in the presence of di-or polysaccharides. Glucose analytical systems employ the enzyme utilizing H2O2 production reacting with Fe(CN)-in the presence of luminol to produce luminescence proportional to the initial glucose concentration
