General description

3,3′-Diaminobenzidine (DAB) is a chromogenic substrate for peroxidase enzyme. It is converted to an insoluble precipitate after oxidation by peroxidase.

Application

3,3′-Diaminobenzidine (DAB) Enhanced Liquid Substrate System tetrahydrochloride has been used:
  • in the detection of hydrogen peroxide in rice leaves
  • as a substrate for rabbit peroxidase in immunohistochemistry of mice brain sections
  • in immunocytochemistry of muscle-derived stem cells (MDSCs)

The DAB (3,3′-Diaminobenzidine tetrahydrochloride) Two-component Enhanced Liquid Substrate System is a precipitating substrate system for peroxidase. DAB Two-component Liquid Substrate System produces a brown precipitate for use in immunohistological and immunoblotting staining procedures.

Caution

Stable for up to 18 mo. when stored at 2-8 °C in the original container.

Quantity

Each DAB Two-component Liquid Substrate System will provide 100 mL of the DAB substrate solution.
