General description

A preweighed vial containing 50 mg o-Dianisidine.

Specificity

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.

Application

o-Dianisidine dihydrochloride is suitable for use in the glucose determination. It is suitable reagent used in the following studies:
  • As substrate for the determination of serum ceruloplasmin from its oxidase activity.
  • Determination of total antioxidant response (TAR) against potent free radical reactions by a novel, colorimetric and fully automated method.
  • As colorimetric indicator for the simultaneous semi-quantitative estimation of glucose, lactate and uric acid on paper-based microfluidic devices (microPAD).
  • Myeloperoxidase activity assay.

Warning

Probably carcinogenic.
