Product Details

Components
The Kit contains the following reagents to make an active stable substrate solution for use with the enzyme horseradish peroxidase:

1. 12 ml Stable DAB Solution (Store below -20oC)
2. 6 ml Peroxide Solution (Store 2-8oC)
3. 6 ml Buffer Stock Solution (Store 2-8oC)
Storage and Handling
Store the DAB (25X) stock solution below 0oC. The remaining reagents are stored at 2-8oC.

Description

Background
DAB Substrate (3,3/-Diaminobenzidine) is the most commonly used substrate for demonstrating the presence of horseradish peroxidase in immunohistochemistry or immunoblotting. It produces a stable water/alcohol insoluble reddish-brown product. The slides may be dehydrated through alcohols to xylene and mounted with any commercially available mounting media.
Directions for Use
1. To 5ml distilled water add 100µl (2 drops) of buffer stock solution.
2. Add 200µl (4 drops) of DAB stock solution.
3. Add 100µl (2 drops) of Hydrogen Peroxide solution. Mix well. (Working solution stable for at least 6 hours at room temperature.)

Application For use as an insoluble substrate for horseradish peroxidase. This substrate solution is suitable for use in immunoblotting and immunohistological staining procedures.
Hazard Description
Caution: DAB is a possible carcinogen. Avoid contact by using gloves and mask when handling.
