Reagent used in colorimetric analysis of Se and other metals.

D5905 

Application
Reagent for spectrophotometric determination of selenium.
Reconstitution
Dissolve 1 tablet in 15 ml of Tris-buffered saline, pH 7.6. Add 12 μl of fresh 30% hydrogen peroxide. DAB and hydrogen peroxide concentration may be adjusted to suit individual applications.
Specificity
Peroxidase substrate suitable for use in immunoblotting and immunohistological staining procedures. This substrate produces an insoluble end product that is brown in color and can be observed visually.

Application
DAB (3,3′-Diaminobenzidine Tetrahydrochloride) Liquid Substrate Dropper System is a precipitating substrate system for peroxidase. The DAB liquid substrate dropper system has been developed for use in immunohistological staining of tissue sections fixed to slides.
Caution
Stable at least one year at 2-8 °C.
Quantity
Each DAB liquid substrate dropper system will provide ten individual application dropper bottles of 10 mL of a fast and convenient DAB substrate solution.
General description
DAB (3,3′-Diaminobenzidine Tetrahydrochloride) Liquid Substrate Dropper System has been developed for use in immunohistology and immunoblotting procedures as a precipitating substrate for the detection of peroxidase activity. DAB is the immunohistology substrate of choice because it produces an intense brown stain that is easily observed. The end product is resistant to alcohol, therefore, a variety of counterstains and mounting media can be used with the DAB Liquid Substrate Dropper System. DAB Liquid Substrate Dropper System provides all of the chromogen and buffer/peroxide solutions needed to produce a fast and convenient DAB substrate solution.
