Description

Biochem/physiol Actions

o-Dianisidine (3,3′-dimethoxybenzidine) is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is yellow-orange in color and can be read spectrophotometrically at 405 nm. The reaction may be stopped with 5 M HCl.

Preparation Note

Dissolve one tablet in 60 ml of 50 mM phosphate-citrate buffer, pH 5.0. Add 12 μl of fresh 30% hydrogen peroxide immediately before to use.

A low serum ceruloplasmin concentration is considered diagnostic for Wilson's disease. We aimed to evaluate an enzymatic test for ceruloplasmin oxidase activity and to compare it with the routinely used immunological ceruloplasmin measurement. Serum ceruloplasmin was measured enzymatically with o-dianisidine
