What is the solution stability of Product D5637, 3,3´-Diaminobenzidine tetrahydrochloride hydrate (DAB)?
1 answer-
In our experience, solutions of DAB should be made immediately prior to use for best results. If and only if necessary, solutions can be kept in the dark and refrigerated for overnight storage. Based on our Immunology Department’s experience, storing the solution overnight did not give good reproducibility. However, the literature indicates that it is possible to store solutions of DAB at -20°C. DAB dissolved in Tris buffered saline (pH 7.6) at 0.6 mg/ml was reported to be stable for several weeks at 4°C.

Do you have a staining protocol for Product D5637, 3,3´-Diaminobenzidine tetrahydrochloride hydrate (DAB)?
1 answer-
Dissolve 10 mg in 15 mL of Tris buffered saline, pH 7.6 (Tris-buffered saline tablet, Sigma Product No. T5030 may be used). Add 12 uL of fresh 30% hydrogen peroxide (Sigma Product No. H1009) prior to use. Solution may be filtered through a 0.2 micron filter immediately prior to use if necessary. DAB and hydrogen peroxide concentrations may be adjusted to suit individual applications. The stain can be enhanced with Ni. Make up 0.3% (w/v) NiCl2 in water. Add 1 mL of the NiCl2 stock to 9 mL DAB solution.

What is Product D5637, 3,3´-Diaminobenzidine tetrahydrochloride hydrate (DAB), soluble in?
1 answer-
DAB HCl is soluble in water at 50 mg/ml yielding a clear to slightly hazy solution. For consistency, it is important to allow DAB to come to room temperature before making solutions. Water quality is extremely important, so only high quality deionized or distilled water should be used to make DAB solutions.
