| Application | SIGMA FAST™ DAB (3,3'-Diaminobenzidine tetrahydrochloride) with Metal Enhancer Tablets have been developed for use in immunohistology as a precipitating substrate for the localization of peroxidase activity. The DAB reaction is enhanced by the addition of CoCl2 and produces a more intense stain which is resistant to alcohol. |
