      Suggested Procedure for Immunohistochemical Staining Using DAB:

      1. Complete all required incubations with antibodies and HRP-labeled probes, and all necessary wash steps.
      2. Prepare 1X DAB Substrate Buffer: Add 9 parts distilled water to 1 part 10X DAB Substrate Buffer (Cat. No. 281753). Mix well. [Note: 1 M Tris-HCl, pH 7.6 may be substituted for Cat. No. 281753, such that the final (1X) concentration is 100 mM Tris-HCl, pH 7.6.
      3. Prepare 1X DAB Substrate Solution: Add 1 part 50X DAB Concentrate and 1 part 0.5% H2O2 to 50 parts 1X DAB Substrate Buffer (prepared in Step 2). Mix well and protect from light.
      4. Following the final wash, completely cover tissue sections with the 1X DAB Substrate Solution (prepared in Step 3) and incubate 5-15 min at room temperature. Note: Variables associated with assay conditions will dictate the proper reaction time.
      5. After reaction is complete, wash tissue sections thoroughly in distilled water.
      6. Counterstain with hematoxylin if desired.
      7. Dehydrate in graded alcohols, xylene, or xylene substitutes.
      8. Mount tissue sections using xylene-based mounting media.

      4. Following the final wash, completely cover membranes with 1X DAB Substrate Solution (prepared in Step 3). Incubate 5-30 min at room temperature.
      Note: Variables associated with assay conditions will dictate the proper reaction time.
      5. After reaction is complete, wash membranes thoroughly in distilled water.
      6. Air-dry membranes and store protected from light.

      DescriptionPeroxidase substrate that forms an insoluble, brown precipiate. Supplied as a 50X concentrate. Designed for use with DAB Substrate Buffer (Cat. No. 281753).
      BackgroundSince first introduced by Graham and Karnovsky numerous procedures for the use of DAB for detection of horseradish peroxidase (HRP)-labeled probes in histochemistry, immunohistochemistry, western blots and dot blots have been described. In the presence of horseradish peroxidase and hydrogen peroxide, DAB is oxidized to a brown polymer that is insoluble in most organic solvents. Thus, xylene-based mounting media may be used for immunohistochemical applications. Sites of HRP activity on tissue sections and blots appear as brown-orange deposits. The color can be modified and intensified by treatment with salts of silver, copper, nickel, cobalt and osmium. This DAB substrate preparation is a stable, convenient, liquid concentrate in a proprietary solvent. The stabilization system prevents formation of partially oxidized DAB, thus eliminating the nonspecific binding to other heme-containing proteins so often observed with powdered DAB preparations. The concentrate can be diluted in appropriate peroxide-containing buffers, providing the researcher with the capability of formulating any of the numerous published DAB reaction systems.
