      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.

      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 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.
