Thermo Fisher, 34065, Metal Enhanced DAB Substrate Kit

Quantity: 275 mL of 1X working solution
Unit Size: Each
The color produced by DAB (3,3'-diaminobenzidine) can be intensified by the addition of metals such as nickel, copper, silver and cobalt that form more dense complexes upon reaction in HRP-peroxide substrate reactions. The near-black signal (precipitate) is easy to photograph. Highlights:
• Incredible sensitivity– 50 times more sensitive than the traditional DAB method and 30 times more sensitive than other metal-intensified versions of DAB
• Low background, high intensity– get a crisp dark brown-black precipitate and, even with the increased intensity, background is almost nonexistent
• Six-hour stability– working solution is stable for more than six hours at room temperature Includes:Metal Enhanced DAB (10X), 25mL; Stable Peroxide Buffer, 250mL
