o-Dianisidine dihydrochloride → Hexose

Participants

Reaction Steps

The assay was based on the method described by Sullivan and Ikawa (Biochimica et Biophysica Acta, 1973, 309:11-22), but modified to run in microtiter plates. An assay mixture contained 150 μl β-D-glucose (0.1 M in 0.1 M sodium phosphate buffer, pH 6.3), 120 μl 0.1 M sodium phosphate buffer, pH 6.3, 10 μl o-dianisidine-dihydrochloride (Sigma D-3252, 3.0 mg/ml in H2O), 10 μl peroxidase (POD) (Sigma P-8125, 0.1 ml in 0.1 M sodium phosphate buffer, pH 6.3) and 10 μl enzyme (HOX) solution. Blanks were made by adding buffer in place of enzyme solution.
