Descripción general
El tetrahidrocloruro de 3,3′-diaminobencidina hidratado es un cromógeno comúnmente utilizado en inmunohistoquímica y otras técnicas de tinción para visualizar la presencia de antígenos o anticuerpos en muestras biológicas. El HCl de DAB está diseñado como un colorante inmunohistológico para visualizar la actividad peroxidasa en las células. La oxidación de la DAB puede medirse utilizando un espectrofotómetro.
Aplicación
El tetrahidrocloruro de 3,3′-diaminobencidina hidratado es adecuado para procedimientos de tinción inmunohistológica, inmunoelectrotransferencia y FISH (hibridación fluorescente in situ). La DAB se utiliza en el estudio de la apoptosis de células epiteliales en caso de cataratas tempranas, y en protocolos de inmunohistoquímica de la enfermedad renal poliquística autosómica dominante (PKD).
Acciones bioquímicas o fisiológicas
En la reacción de la peroxidasa, la DAB sirve como donante de hidrógeno en presencia de peróxido. La DAB oxidada forma un complejo insoluble de color marrón.

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 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.

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.
